This is one of three triathlon training plans created exclusively for Coach by endurance coach Steve Whittle. The sprint triathlon training plan is aimed at first-timers and then there’s the half Ironman triathlon training plan for more experienced triathletes.

“This plan is aimed at people who are looking to take the next step up having completed two or three sprint distance events,” says Whittle. “With this in mind, it’s 12 rather than 10 weeks long.”

How long is an Olympic triathlon?

An Olympic triathlon consists of a 1.5km swim, 40km cycle and 10km run.

12-Week Olympic Triathlon Training Plan

This is a straightforward training plan with sessions measured by duration, rather than a distance to cover or intensity to hit. This will help to progressively improve your endurance, as well as making it simpler to fit all of this training into your work, family and social commitments.
