What Are The Fastest And Slowest Half-Ironman 70.3 Races?

In Part 1 of this series, we found that the difference between averaging finishing times in the fastest and slowest Ironman races from 2017 was nearly three full hours. Are half-Ironmans as disparate?

In a word, yes. The difference between the fastest half-Ironman (70.3 Punta del Este) and the slowest (70.3 Philippines) was a whopping 1 hour and 44 minutes for the average finishing time. Indeed, the 70.3 Philippines was slower than the second-slowest race (70.3 Lake Placid) by more than 24 full minutes. The majority of the blame here appears to lay in the swim. There were 539,105 swims performed in half-Ironman races in 2017, with an average time of 39:18. The average Philippines swim time was 1:03:58, more than 24 minutes slower.

A little bit of digging tells us that there can be an incredibly strong current starting out on the swim, and organizers sometimes even push back the swim cutoff time for this reason. (Indeed, one competitor died on the swim in 2017.) If you do participate in 70.3 Philippines, it would most likely behoove you to find a swimmer going your pace and draft off of them, or, at the very least, take it slow and steady and save your energy.
