I saw this on the ERC site:
"In case you fancy giving it a go somewhere local!
I'm doing the course planning for a mountain bike orienteering event, starting in New Winton on the 16th April. You get a map and 3h to collect as many points as you can. It's not all about speed, strategy and cunning will also play a part.
The course is designed to work for novices or generation teams, as well as stretching racers. No-one should be able to 'clear' it (visit all the controls), but slower people will still be able to create good shorter loops.
Only £15 for solo or £25 for pairs, cake included.
