Five Go Camping: Dusk To Dawn 2012

'Dusk to Dawn' is a twelve-hour mountain bike race taking place each October in Thetford Forest, starting at eight in the evening and running through to the following morning. There are a number of entry types, from solo to four-rider teams. Given that I haven't the faintest chance of sustaining any sort of race pace, or even non-race pace for twelve hours (two usually being my maximum), I entered in a group of four, VC Les Poubelles, comprising Gawain (the organiser), Brendan (the triathlete) and Antony (my brother).

The misery of 2011
It wasn't our first foray into this race, the 2011 event providing a baptism of fire, well, more one of water. On Saturday, a band of rain moved over Thetford in the late afternoon and stayed in place resolutely, only increasing in intensity, until it was time to pack up the following morning. Thetford is normally sandy and well-drained, but on this occasion, became a complete and utter mud bath  On my first lap, I was even fishtailing on the fireroads due to lack of traction and getting any grip on the singletrack sections was only possible by riding up the sides of the puddles in search of any patches of grass. My second lap was a complete disaster, my lights battery dying halfway round the course. I guess that's what happens when you don't charge them between laps! I can't convey the misery of having to push a bike through a sea of mud in zero visibility and it was only with the first glimmers of dawn, at around 7 am, that I could remount and continue riding. That lap took over two hours, twice that of my previous one and guaranteed a low placing; the team only managing seven laps completed.

We just weren't prepared for the conditions and I spent most of the night wet and miserable, desperately trying to absorb some of the meagre warmth of a camping gas light. The conditions ware so muddy, that in addition to needing to jet-wash the bikes after our laps, we had to jet-wash our legs as well! We vowed to return, prepared for all eventualities, in 2012.

Glamping

Camp butler (Not a reference to a flamboyant demeanour)
A key to success in this type of event is a good base. With each rider doing one lap of around one hour, there are three hours between laps to maintain fitness, well-being and enthusiasm  Nothing was left to chance this year. We had a large tent, an 'event awning', generator, electric lights and battery charger, jet-washer and a gas stove for food and coffee. Our rabbit-in-the hat this year however, was our fifth team member, Andy, who for some reason had volunteered to be a sort of 'camp butler', that is to say, chef, bike cleaner and general dogsbody. What a star! I had a good feeling as we set up camp in the late afternoon sun (no rain in prospect this year) and indeed, indulged in the odd spot of relaxation. It was promising to be an enjoyable event.
Contrast to 2011


















The race

While still muddy in places, due to rain the day before, the course was a joy to ride, unlike 2011. The course can be seen in my Strava plot of lap 2, above, and was  a nice mix of fast fire road, wooded singletrack and the odd bomb-hole. For Thetford, which has a lot of stutter-bumps on the singletrack, it flowed pretty well and we put in laps at around the hour apiece. The organisers even put on nice little touches, like playing classical music over speakers and hanging little fairy lights in the trees with about a mile to go which lessened the pain a little at that point.

The race etiquette this year was excellent, with everyone calling which side they were going to pass on, no abuse and just general good manners all round, which improves the feel-good factor. Change-overs were amusing: some riders seem to like clanging the anchors on, sliding, speedway-stylee, to a halt millimetres from the barrier, while bellowing the name of the next rider at the top of their voice. It wasn't difficult to spot your team-mate in the transition area and hand-over the team wristband without the drama, but it takes all sorts I suppose. Most of them did go a lot faster than us, to be fair.

My lap times were 01:01:47, 01:03:23 and 01:05:16, increasing progressively as expected. They felt very different though. Lap one was painful, although it felt fairly fast as I managed to overtake quite a few people. Lap 2 felt fantastic and I thought at the time that was going to be faster than the first. Maybe it was because the course was more familiar, but it did seem to flow better. Lap 3, in contrast felt awful; I just could not seem to get any speed up and was continually being passed by faster riders. I was convinced that it would be at least 20 minutes slower than the last. Funny how feel doesn't reflect the actual speed. I'm always amused at how I handle the bumps on successive laps as a result of exhaustion:- Lap 1: flowing over them in a supple manner, legs complimenting the suspension; Lap 2: letting the suspension do all the work; Lap 3: crashing into everything, while just about managing to hold on!

End of final lap
Overall, our performance was much better than last year, with 11 laps covered in 11:59:22. Yes, we could have done another lap which might have pushed up our position a couple of places above our overall 36th in the four-rider category. Mind you, that was SEVEN laps down on the winning team. The fast guys really are impressively fast.

So, was the experience better, given the improved logistics? Yes, certainly, yet this year's weather problem was the cold. We had a cloudless sky all night and the temperature dropped to around freezing by morning. I tried to get some sleep between laps 2 and 3 and despite wearing my riding gear, my jeans and fleece, jacket, woolly hat and wrapping up in a sleeping bag, inside a car, I was frozen. By morning, fog had rolled in, adding to the feeling of cold and keeping the course slippery until the end. We could have done with a wood-burning stove in the tent, but I think that would would have been a step too far. It would have been nice to have had some source of warmth for getting changed and sitting around between laps, though.

Cheerful younger brother enjoying fog
The 'butler' idea was a mixed success. Yes, he did make the odd cup of coffee and clean a couple of bikes (mainly for other teams), but then he locked himself up in his Lexus, heater on, for most of the night, emerging only for breakfast. You just can't get the staff! Still he did make some decent bacon and sausage sandwiches which redeemed him, I guess...

Overall, I'd have to say we had a pretty good time, but we don't think we'll do it again. There's that awful doldrums period in the early morning that is just plain miserable, if it's cold and/or wet and we're just getting too old for all that. We might have a go at a daytime enduro or perhaps a midday to midnight race next year, but we'll have to see.

Standout kit

Lumicycle lights

The LED lights are fantastic. Lots of light and good battery life  With a bar-mounted and helmet-mounted light combination, operating from the same battery, visibility was excellent. Having a generator to allow between-lap charging meant that there was no anxiety over battery life this year.

Bontrager Mud-X tyres

While there was still a degree of slithering around, these tyres grip brilliantly, don't clog and run tubeless with Stan's. I wouldn't race in mud now without them.

Kestrel Carbon to Burls Titanium

I really must think things through before upgrading. What started as a simple component swap escalated into a major project last year. Despite having a perfectly satisfactory fin de siècle Kestrel 200 EMS, I managed to track down a titanium-steerer EMS fork to replace the steel steerer version purchased with the frame and one I had inadvertently cut down rather too far for comfort. I had always hankered after the titanium-steerer fork and used the refit as an excuse to go 11-speed at the same time, transferring the Campagnolo Record 10-speed kit to my steel Audax/commuter bike. I felt that the alloy Cinelli 64 bars could do with an upgrade to carbon, and  26mm Kestrel carbon bars were chosen to go with the existing Cinelli Grammo stem. I was happy with the result...briefly.
Sadly, when it arrived, the fork steerer turned out to be threaded, with the threads extending to below the lower clamping area of the stem. It went together well enough, and I'm pretty sure that the titanium would have been sufficiently strong, yet there was always the nagging doubt that the outcome of a breakage would involve an inadvertent face/scenery interface (nooo, not the face!) It wouldn't do and besides, the new bars had too much reach and the titanium spacers didn't match the stem!

Despite being state of the art in 1999, the Kestrel had become somewhat archaic, having a 1" steerer. Luckily, Columbus make a light, carbon-steerer 1" fork, the 'Minimal' but there are  no suitable 1" steerer stems available that would work with the 31.8mm diameter of my chosen shorter-reach carbon bars, the sexy Cinelli RAM. In the end, I managed to fit a Thomson X2 stem, using a cut-down Thomson Elite shim, together with some matching alloy spacers, giving a good cosmetic result.

I'm not sure whether it's the combination of carbon bars, stiff stem and carbon fork or whether it's the state of the roads after a cold winter and wet summer, but over the filled and unfilled potholes, fissures and many many stretches of rough chip-seal, characteristic of rural Essex, the bike gave a bone-jarring ride. I replaced the 22mm Continental tubs with Veloflex Roubaix 24mm, which brought an improvement, but really the ride was still as hard as hell and the whole thing just wasn't working: I found I was using my Roberts steel Audax bike in preference, most of the time. Time for a new frame...


Despite any shortcomings, I think the Kestrel was very elegant, as carbon frames go. I'm not a big fan of the current vogue for massive cross-sectioned head/crown and bottom-bracket areas characteristic of modern carbon frames, however and it got me thinking about steel again. When it comes down to it, a steel frame may weigh a couple of pounds more, but always gives a good ride and I much prefer a more traditional look. Who to buy from, though?

This is a rather long preamble into my decision to go for a Burls frame. Justin Burls is based in nearby Harwich, where he has built steel frames and has more recently diversified into titanium. I remember him starting making frames and being impressed by the high standard of workmanship of even his earliest ones, so I made enquiries. It turned out that he wasn't building steel at that point in time, but could provide a bespoke titanium one; the manufacturing being subcontracted to Russia, where the builders had the necessary expertise and experience in fabricating this light but difficult to weld material. It is generally accepted that titanium has a vibration-absorbing ride, it looks great, doesn't require painting and can be configured to taste.

We decided on a road frame, with geometry loosely based on my Audax bike, which I have always found to be very comfortable. I had recently met another rider with a Burls Ti frame and was very impressed by the look of it. He had opted for curved seat stays and fancy tube profiles, which while appealing to my inner bike geek, detracted from the more classic appearance I was after and I decided to go for straight stays and round tube profiles. Forum discussions abound with tales of the flexible nature of titanium and I was anxious to achieve comfort along with lateral stiffness so that there was no front derailleur rub when pushing out of the saddle. Justin recommended 32mm seat and top tubes, together with a 40mm downtube to achieve the desired characteristics. No 'compact' frame geometry either: I prefer a horizontal top tube. The frame is finished off with a curved Easton EC90SL fork which is light and has a nifty internally-threaded star-nut gizmo. Justin provides a CAD schematic to show the dimensions and geometry and even demonstrates that there will be no toe/wheel overlap - a nice touch.

So, does it work? Well, yes it does and titanium really does live up to the hype surrounding it. The frame definitely absorbs harsh road surface vibration, yet has that 'zingy' feel of high-end steel frames. The geometry gives it sharp, accurate steering, yet allows the bike to feel completely stable in long, fast corners. Happily, the frame has no front derailleur rub when out of the saddle, so works just as anticipated. According to my luggage scales, it weighs 15lb with pedals and bottle cages, so while a little heavier than the latest carbon frames, it's still pretty darned light. Any further weight saving is going to have to come from my waistline! Kit is:

  • Campagnolo Super Record 11-speed groupset (2011, with 2010 50/34 chainset).
  • 12-25 cassette
  • KMC X11SL chain
  • 1990's Shimano Dura-Ace SPD pedals
  • 1999 Campagnolo Nucleon wheels
  • Veloflex Roubaix 24mm tubulars
  • Thomson Masterpiece seatpost & seat tube clamp
  • Selle Italia SLR saddle
  • Chris King No-Thread headset
  • Thomson Elite X2 stem
  • Cinelli RAM bars
  • King Cage titanium bottle cages

Is that it, then? Well I'm not sure that the bars are the best design ever. They're very stiff and transmit vibration, routing the cables is a nightmare and they're, well, just too 'frou-frou'! I think the new Thomson road bar would work very well, but that will have to wait for a while. Apart from that, the bike is fantastic, a joy to ride and one I expect to keep for a long time.

I would recommend Burls highly: the frames are of very high quality and are priced very reasonably. A frame like this one will come in around the thousand pound mark, plus fork, which while not cheap, represents outstanding value compared to a lot of high end carbon frames, American titanium frames and indeed many custom steel frames.
