Did anyone see that MBUK article many years ago where they did a reverse bungee jump (ie tie you up, hold you down, stretch the rope, then let you go) on a bike? And then there was one a few years ago where the two Martins rode bikes up trees? Well i'm thinking that bike rock climbing might be a sport to consider, you'd just need someone to be able to belay really fast, and it saves on equipment costs (you only need one helmet!). How good would that be?!
Adventure racing though? Well I'd like to see an under 18s category like they do in most normal mountain bike racing. Surely if there's a parents signature then there's no problem there? There's one for the red bull challenge isn't there?
