There is some high quality nit-picking going on over at MTBR with regards to friends and family showing up out on the trail during an unsupported event. The thread is interesting, but I think borders on crossing some lines. Namely, I don’t want to see these unsupported rides and events become overly governed and policed. I don’t want to see more rules and regulations. I think the idea of “Do it yourself” is fairly clear.
Again and again it just comes back to the integrity of the rider. If a rider wants to cheat, they will. All the rules in the world won’t prevent that.
