I just finished my first no drafting event: Cancun Ironman 70.3 and was very careful about not cheating and keeping my distances in the bike segment. I actually was excited at the idea of doing it all by myself. I was very disappointed when at least 4 "Tour de France" pelotons with 15-20 people passed me and didn't get any penalties. Is this normal? What are your ideas?
