I havent really had that much official MTB experience and havent done singletrack or anything like that, sad I know lol.

But when I used to go out with the bike club we went round Debdale Reservoir and that to me was "technical" as there were pretty big slippery puddles and the track was pretty winding round trees and very tight and had roots which had to be ridden either round or over as well as a couple of steep slopes to ride down.

Wouldnt be much for seasoned MTB riders but it took us a lot longer than we thought to ride round it and it was tiring, muddy and lots of fun
