Most tris do not allow drafting on the bike three lenghts back. Here is the bugaboo- the Olympics do, and now some races allow it because of that. Yet the bike that I was on has been ban from UCI events due to its so called advantage? Go figure how the UCI works. Drafting yes, innovative design no. The tri I do there are no real rules people were all over the road! That though is what makes it fun, I was not the only one who was clueless.
