There’s a demo day being run by a local bike shop on 7 February (funnily enough there’s a trail day that day too), but I don’t think there was anything happening this weekend.
I organise the volunteer repairs to the trail and while the state they get into can be pretty depressing, on balance I don’t have a problem with people using the official trails in winter – that’s what they are there for. I wish people would go a bit easier on the unofficial trails in the winter but it’s hard getting the message out without sounding preachy. The local bike shops have always been very supportive of us, including Zero G, the one that are having the demo next weekend, so I don’t begrudge them using the trails.
