Triathlon coaching

Triathlon, from sprint to Ironman

I raced every distance from Olympic to Ironman. Today I prepare athletes for their first triathlon, a personal best or a world championship qualification.

How I coach

The plan is only the start

The most important part of coaching is what happens after you get the plan: I follow every session you complete, get in touch when something looks off and change the plan when your week changes.

Follow-up and communication

I review every completed session and your comments. Travel, illness or a busy week at work: you let me know, we agree on the next step and the plan adapts.

Feel before numbers

Power, heart rate and pace are a check, but a big part of your training is done by feel. That way you can judge your effort on race day, even when the numbers don't tell the whole story.

Three disciplines and race day

Swimming adapted to the conditions you have, bike and run fitted into a week around work and family, and a pacing and fuelling plan before the race.
