1:16

Overall average Ironman swim time.

:51

Fastest average swim time, set at the inaugural Ironman New York in August. Aided by the “downriver” current of the Hudson River, it’s the fastest overall swim average of any Ironman by more than 10 minutes. The fastest male pro, Luke Bell, swam a 39:08.

1:04

Ironman Australia average swim time, the next fastest 2.4 miles after New York—could be attributed to Australia’s strong swim culture.

1:33

Slowest average swim time, at Ironman Malaysia, potentially affected by breathing difficulty in the humidity.

Based on analysis of 100,000 finishers at 32 races from 2010–2012.
