SA's most technical MTB race?

[Hairy]

so you used the third gear in single speeding!

 

I did it on a single speed! Wore out my shoes on the Monster. Had to walk a good 60% of it. The rest of the race was awesome. Was doing so well until that climb. Took my 2 hours.

Possibly Rotsvas.

I haven't done a race there, but have ridden there. Not the techiest place I have seen, but certainly harder than anything I have seen in a South African marathon event. Lots of slow speed rocks, some trials skills needed, and lots of concentration to clear some sections. Some nice rocky climbs too where you have to pick a line and hold momentum - you don't often see those sections on climbs, so was a lekker experience.
