As Vulfy says, there are quite a few internationally agreed timed obstacles and we are always interested in finding new and challenging designs. During our Practice & Play days we will usually set up an obstacle of the day from the catalogue and run some timed attacks on it just so that people can begin to get the measure of it. We typically do not make these of fixed dimensions, but just lay something out to suit the space and surface available.
A particular favourite is the 'cats cradle' an obstacle that consists of both straight and offset slaloms and a couple of rotations just to make it interesting.
It's the first obstacle being ridden in this video of Yoshinobu Shiga. It's made up of just 8 pylons, but as you can see from the way that Shiga-san attacks it, it's not short of challenge.
