Hey, I've recently taken to riding my XC bike on the local pump track to help hone my handling ability, and it got me to thinking about how the concept of a short technical track could be better adapted to XC training. At present, my idea is to make a track similar in layout and size to the usual thing, but to incorporate short, fast technical climbs, small downhill switchbacks/chicanes into part of the track, as well as other cross country accoutrements. Has anyone tried this before? if so, what are some tips?
