Race Conditions
With both the male and the female winner setting new course records, it’s easy to guess that the conditions must have been great. In fact, the conditions were good, but not exceptional for Brazil: The adjustment for this year was +18:50 leading to a new course rating of 16:31. As is typical for Brazil, the bike was pretty quick (+15:39 at a bike rating of 11:40), but this year also the run was fast (+6:21 at a run rating of 1:43). I’m not sure why this was the case, maybe it wasn’t quite as hot as it normally is.
Male Race Results
The male race saw the first IM win of Timothy O’Donnell. TO almost lead wire to wire. He was close to the front after the swim, then he quickly took control of the race by posting the fastest bike split and building a 10+ minutes lead into T2. He then proceeded to also post the fastest run split and ended up winning by 18 minutes.

Female Race Results
On the female side, Amanda Stevens is probably okay with not being first out of the water but then winning overall. Haley Chura beat her out of the water by more than two minutes, but while I expected her to hold on to her lead, she quickly fell back. (Her bike time was about six minutes slower than expected.) Instead Amanda took the lead with a fantastic bike time – she was about 15 minutes faster than expected and posted the second fastest bike split. She held on to the lead with a 3:20 marathon – the better runners Sara Gross and Jessie Donovan ran well, but were already too far back after the bike to close the gap to Amanda:
