I organised a race a few years ago. It was relatively straight forward.
– I used TLI, they were fine if a little gruff.
– We used timing with a stopwatch and it was mostly OK, a few midfield blunders but there were 100 races and I suspect you won’t get that many. This will make it much easier. If it’s a success you can get more. I’d maybe have a camcorder on the start/finish line to record people going through so you can recheck it later.
– We used race numbers from a running supplier that were sort of coated paper. They did the job fine, mine is still on my garage wall. Very cheap too compared to proper plastic ones, but I think I had to punch the holes myself.
– Use Mountain Rescue for your first aid. We just gave all the profit to them, about £500, and they were pretty pleased.
– Put signs up about the race around the course earlier. Note that it’s much easier on FC land to keep the trails officially open but with some marshals at each entrance to suggest alternatives as opposed to closing them which requires another license.
– If you’re doing it on FC land you need separate licenses for every bloody thing – portaloos, opening gates, racing…
– Small companies are very generous. Howies, local bike shops, a few small skate/surfwear companies, Fisher Outdoor and Rockstar all gave prizes- half the field ended up with stuff.
– If your local bike shop asks Madison they will give you free rolls of Shimano barrier tape to mark the course.
– Have a prize for best stunt somewhere where a crowd will congregate. This went down a storm at ours.
