At the request of a reader we’ll do a little tip on aero positions. We will, however, refer you to a great photo essay at Slowtwitch. They took amazing pictures of some of the best Pro athletes at the Hawaii Ironman World Championships this year. (Unfortunately I can’t find the link to that particular article - but here’s another with some pictures for your interest.) If anyone happens to find the other article please feel free to leave a comment pointing the way.
Our take on aero positions (like most) is to be as aero as possible without compromising your power. Aerodynamics are indeed important, but time saved due to less drag will pale in comparison to the time you lose if you are so uncomfortable you can’t ride properly, or if you hinder your ability to run afterward. Here’s a couple pictures to show you some extremes on either end of the scale.
Bjorn Anderson – This position is CRAZY. It works for him on the bike – but it’s hard to say what it costs him on the run. He usually has the fastest bike split outside of Kona, but rarely has a good run. He did win Wildflower, but I think his Ironman attempts have been lackluster. Maybe he can’t digest food properly, maybe he rides too hard. Whatever it is, the point is to show a very extreme aero position:
