Plan A is that we'll use my Shiny! New! sprint timing system to do some 50m flying sprints down the long straight (clockwise, I think, so as not to finish into the hairpin).  Consider this to be a test of prototype hardware/software in advance of the World Championships next year: While we had a successful field test in the local park last weekend, it's entirely possible that new problems will emerge with HPVs moving at speeds significantly faster than I can pedal my Dawes on sketchy gravel (especially if we have to use my cheap Chinese optical sensors).  If the system works properly it should automatically identify riders using the RFID system and upload the results to the live results page in approximately real time, without any tedious data entry.

NB: For this to work properly it's imperative that riders keep their tags away from the timing area except when sprinting.  Unlike a race, where it only corrupts your own lap times, you could potentially claim other people's sprint results by introducing stray tags.

Plan B, if we determine that Plan A isn't going to work soon enough, is to run another 1-lap time trial instead.  If we end up with incomplete sprint results but no time for a time trial, the sprints will get 0% points weighting.

Either way, we're going to aim to get started at 10:30 or so, but this is obviously subject to taking a bit of time to get everything set up and tested.

And then in the afternoon (let's say a 12:30 start, so we can be off the track by 15:00), we're going to do a 2-hour criterium race, with everyone on the track together.  Anticlockwise, for a bit of variety (and with luck a mild tailwind on the straight).  Bring an empty bladder and hope the cramp fairy stays away...

It seems that people enjoyed the sprints (particularly when you get the result immediately via the Laser Display Board™ and live results webpage), so I expect we'll be doing this again in future, not just for the Worlds.

Disclaimer: The sprint timing should be precise to somewhere below 0.1 millisecond, but the trap distance was eyeballed based on the length of the 49.5m[1] extension cable, so the calculated speeds - while consistent between riders - won't be entirely accurate.  One of those measurey wheel things is on the to-do list for future events.

Meanwhile, the 2-hour race went reasonably smoothly, and Natalya seems to have managed to thwart the Watsons' efforts to confuse the timing team.  As usual, let me know if something doesn't look right.

[1] By the time you've terminated both ends of a 50m cable, it's sadly no longer 50m long.

Does anyone want to claim these socks?  One was seen lying on the parking area in the vicinity of our tent for much of Monday, and I found its twin on the manhole cover behind the toilet block later in the afternoon, so brought them home and washed them.
