New levels of crazy here. I was reading Stu Middleman’s book Slow Burn this morning and he mentions that he started doing triathlons in the early eighties because he thought it would make him more marketable. So he competed in both the 1983 Hawaii Ironman and two months later competed in the Ultrathon – which is a double ironman.
So I went looking for Ultrathon, and couldn’t find anything, but looking for double ironman I found these results, which include a triple ironman. That is seriously insane.
