It ain't what you do

I did the longest ride in a few years yesterday- 40 miles on the St Albans Rotary Charity ride, riding north from St Albans towards Hitchin. It wasn't a huge distance compared to what most club cyclists do every weekend but for someone more used to a 5 mile commute and a few 20 mile rides it was plenty! The ride went well, even though my average speed was a bit lower than what I was expecting. There were a couple of steep hils- I walked one just outside Preston but scraped up the other steep climbs, including a 1 in 10 just outside Kimpton which I was quite happy with. There were a few good downhills too, clocking 36.9 mph freewheeling down one of them. My power-to-weight (or more like my weight to power) ratio isn't exactly optimal for hills...The weather was kind - the forecast rain held off until after I'd finished, though it could have been a bit warmer.

There were plenty of people riding too, though most were doing the 10 or 20 mile version. Plenty of kids out there too, including one boy riding with his dad wearing Welwyn Wheelers kit- chapeux to the youg fella as he was keeping well ahead of me for the entire circuit. It would be nice to get my kids up to that level, I'll have to work on that one over the next few years.

It was good training for Ride for a Reason next month. You are sponsoring me on that, aren't you?...

Wednesday, September 19, 2007

Last night's commute was great; a nice steady spin through the lanes, spotting the changing colour of the trees as Autumn entres stage left. The last bit of this particular route takes me home along what is locally known as the St Albans ringroad; it's not the most direct route from the lanes, just a little loop I add in to squeeze another mile or so into the ride.

Despite the name, the 'ring road' is not really that grand, just a set of normal streets which link to run round the north side of the city about two-thirds of the way out. Traffic can be busy, but it's not intimidating. Close to home there's a couple of mini roundabouts about 75 yards apart; at this stage in my commute I'm well warmed up, the road is flat to slightly downhill and I'm riding fairly quickly (about 18-20mph), maintaining a distance of about 4 feet from the kerb to set myself up to turn right at the second roundabout. My speed and the distance between the two roundabouts means that I'm not holding up the traffic to any real extent and traffic in the other direction usually prevents safe overtaking.

Anyway, last night I'm about 3 feet from the kerb approaching the first roundabout when a van starts to overtake (pretty stupid thing to do, but no problem, I have space to move into if needs be), then pulls in sharply to within 18" of me when it's half way past and almost up to the roundabout (big problem). I slap the side of the van, not hard, just enough to let the driver know I'm there, and shout 'give me room!'. The driver bakes, and I clear the roundabout ahead of him. This is red rag to a bull to the driver, who then sits on my back wheel tooting his horn and follows me as I turn, keeping up the agression and the horn. As we approach a parked car he's nearly parallel and it looks like he's going to box me in. I'm on a road bike, so hopping the
kerb isn't really an option and I stop before we get into a road duel which I'll only lose. Most of all, I don't want him to follow me home.

The usual enraged cager diatribe ensues; I tell him he was too close, he threatens to 'slap my face like I slapped his van' and follows up with the tired old 'you shouldn't be on the road, you don't pay road tax, don't have insurance, yadda, yadda yadda.' He's virtually foaming at the mouth, won't admit he pulled in on me at the roundabout, won't listen to me, so I just let him spew his bullshit and calm down a little before saying 'whatever' and riding off unfazed.

There's no solution to this sort of outburst which doesn't invite further agression, so there was no point in continuing the 'conversation'. In retrospect I'm slightly annoyed I forgot to pull my phone from my jersey poket and video the encounter to follow up with his employer, possibly "CV plumbing" or similar but I couldn't be sure- a plumbering/heating firm in any case.

This incodent isn't a big deal, I've commuted by bike for more than twenty years, I'm well used to this sort of thing and it doesn't happen often. What bothers me is the degree of ingorance and bigotry and the downright agression of a small minority of drivers.

We need a local road strategy which educates drivers about leaving adequate room for other road users, and infractructure design/signing to reinforce the message.

On the other side of the Atlantic, blogger Cycledog writes about simialar attitudes in the US and references analysis which refutes the 'freeloading cyclists don't pay for the roads' myth.

and . . . . relax.


and . . . . relax., originally uploaded by mike1727.

It's the end of my second week of higher intensity bike riding, and for the first time so far I'm feeling tired. Tired, but at least not aching; with a couple of 'red mist' exceptions, I've been targeting lower intensity, longer rides in low gear rather than mashing big gears. I still can't climb worth a damn, but that'll come once I've got better basic fitness and shed a few pounds.

The 'plan' (a very loose interpretation of the word) is to spend about a month more just getting miles in my legs before upping the intensity to the next level by working more on hill climbing. The daily commute is up to around 7 miles each way and I'm doing two or three lunchtime sessions of about 11-12 miles. It's not really enough for base training as none of the sessions are longer than 40 minutes, so I'll chuck a few hours a week on a turbo trainer into the mix in a couple of weeks' time.

Here's the stats for the first couple of weeks. Don't laugh, I'm starting from a very low base! Some of the data is a bit suspect since my HRM seems to randomly corrupt samples.

Week 1 week 2
Mileage 75.4 89.9
Rides 12 14
Calories 4135 4357

Av heart rate 147 147 (in the 'fat burning and re-energise glycogen' zone. Ha.)
Max heart rate 171 170 (approx 90% of estimated max)

av speed 15.9 16.7 (not my primary target but nice to see an increase)

The target for next week is 100 miles, which should be easily achievable if it doesn't rain too much.

Days until I'm 40: 23.
Age-related angst level: amber.

This is a photograph I did not take

of a group of mountain bikers crossing Nomansland Common the other evening, the car's headlights rendering their identical reflective jackets into a long dotted line as they ride west along the arrow-straight single-track lane, equally spaced with almost military efficiency. Unbunched, each rider in his/her own 10 yard bubble, they don't appear to be 'normal' cyclists.

With a tip of the hat to Unphotographable.

Symondshyde access track improved.


Improved, originally uploaded by mike1727.

I've never been a fan of trail improvements done by non-cyclists. A fat design manual and a love of straight lines and smooth surfaces means these 'improved' trails lose the character they had, changing from interesting to bland, packed dirt to rolled crushed stone.

Farm tracks are another matter. They take tractors, for a start, and this means ruts and mud. This section used to be badly rutted and pretty swampy in winter; nothing impassible, but not a section you really want to ride at 8am on a wet January morning in the knowledge you'll have to wash the crud off the bike again that evening. It was a bit challenging to ride in the dark at times too.

Now it's looking weather (and tractor) proof, with a crushed stone surface which should stand up to the equestrian traffic too.

Thank you, trail pixies.

oybike

Spotted these just round the corner from West Kensington tube station as I was en route to a meeting.
Oybikes are rental bikes, available at selected locations around the city, though unfortunately concentrated in certain districts. The bikes are locked to special stands until activated by a PIN sent to registered users via SMS. The bikes I saw were well suited to city use with light, basket, mudguards and shaft drive (to avoid those chain oil on suit leg moments), and these ones at least seemed to be in good working order.

Given the nightmareish tube journey I had yesterday (20 minutes became an hour due to problems on the line I wanted to take), I'd have been better off travelling from Kings Cross to West Ken by bike. There's an OYbike rank on Euston road, just down from King's Cross station where I'd usually arrive by train; not on the station as I'd expect, but down the road outside a hotel.

Commute riding in an unfamiliar city can be a bit of a challenge. As an out of towner who usually travels by tube, my mental map of central London doesn't really focus on above ground journeys longer than a mile or two, so navigating and dealing with heavy city centre traffic can be stressful. As a result I often take the easier option and look for bike route and backstreet options which are more roundabout but often much more interesting. I'm sure this is the case for many of oybike's customers, and it's in oybikes interest to extent usage beyond the 30 minute free period.

So, you'd expect a bike2.0 outfit like oybike to at least present a 'quiet streets' option on their website routefinder then? Nope. The google-powered mashup the oybike site uses routes you down the major streets between the two destinations, not the quieter backstreets, and there's no easy way to change the route criteria to suit a bike.

The Transport for London site gives a better route.

Via the STACC Blog:
Part of liftshare, BikeBudi aims to match up cyclists riding the same route. It's an excellent way to build up commuting groups (which was how critical mass got started) and for experienced riders to help new riders gain confidence on the roads. It's an excellent idea.

If you don't fall off you're not trying hard enough


Ouch, originally uploaded by JasonRogers.

Jason and me went for a ride last night. I'd planned for an easy loop round St Albans, pootling round singletrack in Batchwood, Symondsyde and points between. We had a quick look at Beech Bottom Dyke on the way to Batchwood, me scaring myself silly at the size (30 feet approx) of the drop from the trail into the earthwork. Onwards and just about upwards to the woods at Batchwood for a quick blast on the singletrack before heading off towards Harpenden and the rest of the loop. As we headed though Childwickbury we were caught up by a group of 8ish riders from one of the local shops, so we tagged along for a while, finding a couple of new linking trails through Sandridge to Symondshyde. At Symondshyde the main group was heading up towards Codicote; feeling tired I made my excuses and we headed back through the woods. Pretty much the last stretch was down a track leading onto House Lane. It's fairly smooth (apart from the collapsed badger sett half way down) and I ride it at least twice a week on the way home, so I shouldn't have had any problems..not so. Approaching the junction with the road and braking fairly hard I had an earth/sky/earth/sky moment, ending up braking with my chin as the bike flew over me and landed three or four yards further down the hill. Winded, but bike OK and no bones broken I picked myself up and we headed back to my place via the off-licence.. Woke up this morning with a few random achy bits and bruising, no big deal.

So...what did I learn?

  • Commuting 20-30 mins each way every day does not give you the fitness required to keep up with the shop riders. More lard-burning miles required!
  • I brake far too much in corners and need to trust the bike and flow round more.
  • Don't touch the front brake on dusty fast bits!

Carniverous V-Brakes ate my rim

Another rear rim falls prey to the ravages of winter road grit and year-round Hertfordshire mud (with added flint dust for extra abrasion).
Disc brakes are looking more and more like a good idea, but at a high price- fitting them would mean new brake levers and shifters on top of two new wheels.
The green travel legislation which underpins the company bike scheme won;t help- employees can't buy accessories without a bike, and I don't really need another bike. No, let me rephrase that, I obviously need more bikes /, I just can't justify the spend. It is possibleto buy a cheap'n'nasty £80 Halfords bike just to be able to save money on accessories though...hmm.

Give me a child until it's seven and I'll give you the cyclist




We went to meet a bunch of the childrens' friends at a local park the other day. It was a warm, sunny afternoon so the park and play areas were swarming with kids, many of them riding bikes. There didn't seem to be the same penetration of bikes into the older groups of children.

This got me thinking-At what stage in a child's development does cycling start to become less frequent, and why? My sunny-day-at-the-park sample is fundamentally flawed, but bike usage seems much higher in early years (say 3-6) than it is later in childhood and adolescence. There seems to be a strong correlation between leisure activity and cycling in early years (Mum & Dad taking a child's bike to the park) which isn't strongly carried through into utility transport in later years. You don't see so many kids going to Saturday morning football/swim class etc on a bike, or cycling to school, and I'd bet that fewer families go for bike rides together than take their young children to the park with their bikes.


Factors like increased distance, changes in environment from park to road, perceptions of danger, fashion and increased complexity of journeys all play a part, but in the end what's lacking is the perception of bikes as a real, practical means of independent transport rather than a just another toy to compete with the playstation. This perception gap is key to getting more people on bikes- and it needs to be addressed early.

James Daley writes about the Cycling for London's Cycling Community and Emergency Services Awards in the Independent's cycling column:


Liz Bowgett, a teacher from Newham, for example, took it upon herself to get more children in her school on to two wheels. After announcing plans to launch a programme to give children some basic bike training, she found she was oversubscribed three times. Within a few months, she was managing a full-scale project: organising mass bike rides, building storage facilities for bikes at the school and buying a trailer to transport bikes for trips away, as well as buying second-hand bikes for those children who didn't have their own.


This is a great example of grass roots work on cycling, building and maintaining interest in cycling through enablers and involvement, linked into the school curriculum. It's the way forward if we want to build cycling locally, but this example clearly shows it won't happen by itself...this is where local cycle campaigns come in!

Bike quiz



The BBC's magazine site has a bike quiz. It's fairly noddy, but there are a couple of tricky questions, so I didn't get full marks.

Misty morning commute


Misty morning commute, originally uploaded by mike1727.

7:15- breakfast. "It's a lovely day, aren't you taking your road bike this morning Dad?" "No son, I'm riding the woods today"


The spring solstice has come and gone, leaving behind it daylight saving time as a reminder of the changing season. This morning is cool, still and fresh. A deep red sun glows through the mist as I wheel my bike out of the garage and coast down the hill with the children's shouted goodbyes ringing in my ears. Which route to take...road..trail..woods? Thirty seconds later I'm turning off the road into the first strip of suburban woodland, weaving through the trees, dropping in and out of small chalk pits and hopping over trunks of trees brought down by the winter gales. This section is short and easy, but coming so early in the ride it's always a good wake-up call.

Out of the trees, up the alley, lift the wheel for the step up onto the road, cross to the next section of bridleway which the kids and I walked the other day, counting squirrels and looking for treasure. Thirty seconds later cross another road, faster now on a smooth bridleway past another pit where the carcass of last year's pantomime cow decays gracefully, papier mache flesh falling away from its wooden skeleton. Cross the lane, carve a line past a sleepy schoolboy texting on his way to school. Keep the speed up, unweight and float the first drying-churned-mud bumpy section onto the footpath skirting a field of winter wheat. This was muddy drudge riding a month ago, but dry and worn smooth by tyres, paws and feet it rides fast today. Float more bumps past the mist shrouded pond where coots stand on the bank taking stock of the day, more narrow fast singletrack to another lane. Cross the road to the next bridleway, down to the middle ring for the hill because I'm still warming up and not in hero mode. Easy spin up, avoid the collapsed badger sett which is a real hazard on dark descents, crest the hill and ride along the ridge, past the clutch of cell towers in a corner of a farm compound full of well-used machinery.

Real countryside now, pause for a photo at the gate at the end of the ridge, cameraphone not doing justice to the view but good enough to record the moment. The first section of tarmac- change up and spin along a single track narrow unfenced lane through the fields. Looks like the farmer's planted wheat this year instead of last year's sickly-smelling rape, good. F*ck, I don't remember that pothole, deep, sharp-ended and wide it must've been caused by the winter frosts. Ten minutes in and the first car of the commute is behind me but hanging back nicely, just as well because it's too narrow to overtake and I'm not pulling in. T-junction coming, I pull in slightly to give it room to get past in recognition of its lack of aggression. It's Simon, he lives maybe half a mile from me and works in the building next door. Brief hellos though the open window- "Get a bike mate" before he's off down the lane. I follow, peeling left through a gate onto the next track. Another muddy rutted nightmare in the wet, it's drying now. Slightly downhill, picking a careful line between the soft bits and the ruts where I stacked last year though lack of concentration.

Right into Symondshyde Wood, smooth flat bridleway, 'improved' with a crushed stone surface last summer. Birdsong in the tree canopy above, bluebells pushing through the leaf litter and sticks below, a blue carpet waiting for late April. The bridleway is the boundary of a strip of beech, I'm riding though tall commercial pines now, muddy patches, narrowing. Shots in the distance, bird scarers perhaps- there are deer in this wood but I think it's closed season. Passing a couple of familiar landmarks- rusting machinery left over from planting the pines- turn left onto a forest ride. Less familiar, this wasn't the track I was planning to use but it's heading in the right direction judging by the position of the sunlight slanting through the trees. Easy ride down to the lane, left and right through the livery stables onto a long flat farm track through open fields recently ploughed and harrowed to a fine tilth ready for planting. Clock's ticking, short of time. Change up, pick up the pace, spinning fast on the smooth surface. Left and right around the corner of a field bounded by high earth banks awaiting sand quarrying. Looks like we'll get another few seasons before the quarry reaches here. That square green patch of grass on the right used to hide a ROC observation post; post cold war it's filled in and used by radio controlled fliers. 8:21 and I'm pushing pushing harder now, past the clanking conveyor, though the gate and over the road to a disused lane. Faster still, turn hard right over the berm, meandering track through the parkland next to new houses, gravel pinging off the downtube. Cycle lanes through the housing past the postman delivering to mews style townhouses. Ivy Walk, Cornflower walk, Campion road- echoes of countryside which came before the aircraft factory before the houses. Roundabout, first real traffic and last quarter mile sprint to work.

8:27, drop into the underground car park.

Another day, another dollar.

Car(e)-free shopping.



I took the bike trailer into the city centre for the first time for the weekly food shop on Saturday, eager to see how it coped with a load of fruit and veg from the market and happy to be avoiding shopping at Tesco.

Riding in from my house is easy- a round trip of 3 1/2 miles or so on flat roads, following pretty much the same route as I would in a car. Speed is never going to be an issue when pulling a trailer, just trundle along in a lowish gear and take your time, watching out for the extra length on sharp corners. Traffic was light that morning, so I've not yet found out what it's like to progress through lines of stationary vehicles. Once in the city parking was easy, just unhitch the trailer and chain it to the bike rack with the bike- no messing around queuing for a car park and searching for an empty space. There was plenty of room for the trailer, but parking might be a bit more of an issue when the racks are busier- we still need more racks in the city centre to make up for the loss of the railings on St Peter's street. Next time I'll push the trailer round the market to load directly instead of carrying heavy bags- another thing you can't do in a car.

Overall impression- quicker and easier than I was expecting.

A quick comparison of car vs bike costs for the trip- I was amazed by the amount of CO2 a car produces on such a short trip- as much mass as a bunch of bananas!

In the green corner, a bike trailer.
Ride into town- 10ish minutes.
Park on St Peter's Street, just accross the road from the market.

Additional CO2- nil.

In the dirty brown corner, a diesel car.
Drive into town-5ish minutes.
Find car park space, park, walk to market- 10 minutes.
Buy food.
Walk back to car, pay car park ticket, queue to leave car park 10ish minutes.
Drive home 5 minutes.

Link bait..


Hey, guess what?, originally uploaded by mike1727.

A mention for two quality bike resources on 'tinterweb.

cyclelicio.us is a quality bike blog with mainly US-centric bike advocay and commuting bias. Fritz is looking out for bike haikus, here's one which bubbled into my conciousness while I fixed my latest (3rd in a week) flat last night. At least this time I found the thorn.


Snowy verge hid thorns
Sharpness beneath the smooth white
Holes my tube again

Yes, I know, it's pretty crap.

For audio, the bikeshow from resonance fm is hard to beat- quality journalism with eclectic content. Reccomended listening.

Snowday commute


, originally uploaded by mike1727.

It snowed a bit on Wednesday evening- about 4 inches or so. The roads were suprisingly passable, but I avoided the drivetrain munching salt/grit combination by riding to work offroad. This was surprisingly easy- keep to a middling gear and churn away. The fresh snow was quite grippy, but the thin layer of snow over paviers on the bike path in the office park wasn't, resulting in a couple of unplanned body/ground interections.

Local schools have stayed closed today, which seems a bit of a skive given that the roads are clear. It's the typical British over-reaction to snow- more than a half inch and panic ensues.

Green ink time again?


WATCH FOR BIKES, originally uploaded by psd.

It's difficult to place bike advocacy stories in the local press without coming over as a 'green ink/no margins' nutter. Hopefully this latest attempt (published today) worked..

SIR, - After your recent editorial comment about St Peter's Street, St Albans, it's important to point out that bike lanes and off-road bike routes are not the only way to improve safety for cyclists. Well-designed bike lanes do provide an increased sense of safety for some and do encourage people to take up cycling, but they take a long time to plan and build and can be expensive. Sadly Herts Highways and local and county councils don't have a good track record in St Albans.

The recent development of a Cycling Strategy is a step in the right direction but it will take many years for a usable, linked network of on and off-road cycle routes to arrive. In the meantime, it helps no-one to imply that roads are too dangerous to cycle on when some changes to cyclists' and motorists' behaviour would make cycling considerably safer at little or no cost.

Here are a few common-sense tips for safe cycling on the road, derived from Cyclecraft, the Government-approved guidebook to safe cycling, or from the Highway Code.

Cyclists:

n Don't ride in the gutter. Riding two to three feet away from the kerb puts bikes in a position where they can be seen by other road users and have some safe room to manoeuvre into if needs be. Riding here keeps you away from broken glass and other debris which traffic sweeps into the gutter and causes punctures.

n Always leave a gap when overtaking parked cars - riding into an open car door will hurt.

n Obey red traffic lights, just like other road users. A bike rider is soft and fleshy, other vehicles are hard and heavy. You will come off worse in any collision and you'll have only yourself to blame.

n Stay off the pavement unless there are signs indicating you're allowed to use it. Pavements are for pedestrians, unless you're young enough to be riding with stabilisers. Even if the pavement is clear, you will be more vulnerable to being hit by a car simply because you will be crossing driveways and roads in places where drivers are not expecting to see you.

n Be aware of other road users - making eye contact with drivers at junctions and glancing over your right shoulder to check what's behind you makes you more aware of what's going on and reduces some motorists' tendency to see you as an impersonal moving speed bump.

n Signal when you're turning or moving out - just like everyone else on the road. Doing this helps drivers predict what you're going to do.

n Use lights at night and on dark mornings and wear something brightly-coloured or reflective. The warm glow you feel at using eco-friendly transport does not make you visible to pedestrians or other road users.

n Don't pass lorries and busses on the inside. You may not be visible to the driver and you can be hit and seriously injured.

n Don't mistake the red-painted strips on Sandpit Lane and Hatfield Road for cycle lanes - they're (barely-effective) traffic-calming measures.

Drivers:

n Bikes have the right to be on the road so treat them like other road users. They don't have to use bike lanes which are often badly-designed, ill-maintained and dangerous. All but a tiny minority of cyclists pay taxes which pay for the roads, and many have insurance. (By the way, "Road Tax" hasn't been reserved for road spending since 1927, and even then road maintenance and construction was partially subsidised from general taxation.)

n Leave room when you overtake - passing too close is very dangerous since bikes may need to swerve to avoid potholes which you can just drive over. Do you really need to overtake when all it often does is get you to the back of the next queue 30 seconds faster?

n Bikes can travel quicker than you expect, so don't pull out too close in front of them at junctions or make turns without signalling.

n If you park on the road, look out for passing bikes when opening doors.

n These coloured boxes painted on the road at traffic lights are there for cyclists' safety, please leave them clear.

n Don't park in the few cycle lanes we have.

Thornholio


Bah, originally uploaded by mike1727.

Strewn on local bridleways like natural cathrops , hawthorns are the bane of my off-road cycling life.

In the past 7 days I've had two front wheel punctures, and this morning the back tyre was soft so I've probably got a slow puncture there too. I'm pretty sure of which stretch is causing it- a quarter of a mile of bridleway skirting the northern edge of Marshalswick- the problem is that this is a very useful stretch which links a bunch of other routes.

Anyway. I digress. I have a plan. I'm going to keep all the thorns my tyres pick up this year and ritually burn them on the winter solstice. Hopefully this vodoo anti-wassail won't simply encourage more growth and more punctures the following year..

fillthathole.org - report potholes

Those wonderful people at the CTC have produced a site which allows people to report potholes online using a single site rather than the one which Herts Highways use.

This is an excellent development and would be so much better if the highways agencies shared their data. Herts Highways progress on fixing potholes does seem to be improving, but they're very still bad at making their progress visible. If the various Highways agencies nationwide could/would make their systems open then sites usful mashup sites like this could work to their full potential by showing full detail of all reported faults.

I'm sure that many faults are reported (and probably investigated) multiple times since the public aren't aware of what has already been reported. Making the data public would alose give an independent means of monitoring the progress of agencies funded by tax-payer's money, so I guess it'll never happen.

So- if you see a pothole, report it. Let's get the map full and then hit the local press with a screenshots to shame highways authorities into pulling their collective figers out.

There is a companion site clearthattrail.org.uk which does the same thing for off-road rights of way.
