Here I analyze the technique of a UK based triathlete competing in Olympic distance triathlon. He’s brought his threshold pace down from 1:40–1:45/100m to 1:33 in the last year.

There are two things I’d focus on most if I were him:

1. Breathing: Exhale form the nose and get the head returning back into the water quicker.

2. Rotation: Reduce the upper body rotation to maintain better balance and improve his catch (and stroke rate!)
