Is there a sign on time / race format for York pls?
If not can I suggest:
15mins clockwise
30mins anti-clockwise
4 lap (1km) flying-start time trial (more feasible with only 13 riders)
Russ

Thanks Russ, Its always good to get some input into race organisation. Apparently it is an (unwritten) rule that you always ride velodromes anti-clockwise which is why we did all races that way. A 4 lap flying start might have been better than the fastest lap of 3 but we can try that next time.

I believe some velodromes (fairly sure London is, not sure about York) are actually asymmetric and thus specifically designed to be ridden counter-clockwise only.
Current fleet: Milan SL MK2 #027, Fujin SL II, Beany!

I'm sure I read a few years ago that Manchester was making people ride clockwise in order to even out the wear on the boards, but I strongly suspect it to have been an April Fool or similar joke, jape or gag.

Results!  We haz them!

http://www.bhpc.org.uk/Data/Sites/1/media/events/events22/04york/index.html

Observant readers will notice that the third race appears as both a three-lap time trial and a one-lap time trial.  This is because we used the software in time-trial-timing mode (manually without the RFID system, because reasons) to record that event.  It doesn't have a concept of best-of-n, so I've hand-crafted a fake one-lap time trial using people's best lap times in order to display and further process the data.  Really observant readers will notice that some of the times are different.  This is because we were also recording times with a Mk 1 stopwatch and clipboard, and I've taken the faster of the two best times for each rider.

Now, you're probably thinking 'Never mind all that bistromathics, what about the photo finish between Russell and David in the final race?'

Well, it was certainly close.  Too close for the RFID data to be of any use.  Fortunately, we now have CrossMgrVideo.  Unfortunately, we have a 30fps Logitech webcam, which was plonked on the table behind the computer in the timing tent, and not a high-framerate industrial camera on a tripod aimed perpendicular to the finish line...







It's clear from the surrounding images that Russell was overtaking David as they crossed the line, but with the parallax error, that's too close to call.  So I've done the only reasonable thing and given them both the same finishing time!

And, since the software surprised me by not choking on Natalya appearing twice in the same event (she had a second attempt at the best-of-three with her e-assist battery removed, for multitrack points SCIENCE), I've quickly and efficiently updated the championship tables without any hacking:

Great job, Kim. I was wondering how we were going to score the 3-lapper and your solution seems perfect.

The photo-finish looks like it's down to where their cranks were as they crossed the line so a dead-heat is fair, if the software allows.

(Remembers the time in Roskilde when Dave Richards' body crossed the finish line marginally before that of Johnny FOREIGN but had mounted his transponder on the trailing edge of his tail fairing while the Cunning Continental had his mounted in the vicinity of his front wheel. The rotter.)

I knew it was close, but not that close!

I completely f'd up the end of that race - I found myself on the front of the line with three whole laps to go to the checkered flag and I thought sod it - I'll hold the inside line and they'll just have to come past me the long way. Three laps later I was miraculously still leading, but what there was not was a chequered flag but a sodding bell....aaaaaargh.....1 more lap at full tilt with a lunatic Frenchman bouncing away on the outside resulted in a new all-time maximum heart rate of 185.

I'll take a draw...unless David's camera shows otherwise...

Which by some freaky coincidence is about what my heart rate reached as I failed to hold on to your wheel about a third of the way through.  I thought it reached 190, but it turns out that was during the sprint finish with Jack (alas, no photo needed for that one).

Well the PLAN, such as it was, was to swap the lead a couple of times then for you (probably) to surge past, fully refreshed, into an uncatchable attack. I was as surprised as anyone when you insisted on hanging on heroically in front. Makes for good TV though Clap.
