AdventureKhana

Was watching a video last night where they showed the guy doing a gymkhana on a motorcycle - where you have a course laid out with cones and the rider needs to do certain maneuvers against the clock. So I was thinking, that looks like fun, but maybe something with some off road type obstacles included could be even more fun.. Do a tight u-turn proceed to race up a steep dirt pile or something similar.

Is there something like this already? I think the GS-challenge is the closest to what I'm imagining, but that is more off road focussed I think. Is there road based gymkhana events taking place that I'm maybe just not aware of? Would anyone actually be interested in doing this?
