It depends on your level of fitness/capability but Elite is pretty full on
> B or medium I think. Anyone have experience of these? Which is better to do? How far in advance do you get the maps to plan the route?
It depends on you, obviously. The B class winners took 11hrs over the two days last year, the slowest took 20, lots did not finish. I've no idea of your fitness levelbut being a good "runner" is not enough, plenty of time "trotting" across moorland/over hills away from paths and good nav are what will get you round.
I started outdoing line courses (it's the simplest option) but having done a few score class events this year are growing to like them. If you chose score, you need a good awareness of your speed when covering different types of ground.
I would say pick a course you think you will be competitive, I've enjoyed it a lot more when we're got into to the chasing start and have managed to finish in the top 15 or so, it makes it feel a lot more like a race on day two. There's nothing like seeing B15 storm past you when you've B8 on your back to get a spring in your step and find a surge of pace......
