PERFORMANCE COACHING

You have a goal. A race on the calendar, a distance you've never done, or a nagging feeling you're capable of more.

Endurance PTC coaches work with all levels of cyclists, runners, and triathletes in Marin County who are ready to train smarter, with a plan built around how their body actually works, not a generic template. We focus on you: your data, your plan, your coach.

Most coaching starts with a spreadsheet. Ours starts in the lab.

Every EPTC athlete goes through physiological testing before training begins. We measure VO2 max, lactate threshold, body composition, fat and carbohydrate utilization, sweat sodium testing and more to inform your training zones, pacing targets, and fueling strategy. Your personal coach will work with you to build a plan that delivers results and will support you every step of the way. And as your fitness improves, we retest and adjust.

That’s the personalized approach we’ve used for 20+ years, because it works.

VO2 max

Know your true ceiling

Lactate threshold

Train in the right zones, not estimates

Sweat sodium

Understand your personal needs

Body composition

See what’s actually changing

Do any of these sound familiar?

Big race ahead

You have a target on the calendar and want to arrive genuinely prepared. Not just trained, but confident that you’re ready.

Training isn’t working

You’re putting in the hours but not seeing the gains, or getting injured in the same place every season. There’s a physiological reason for that.

Moving up in distance

You’re tackling your first marathon, 50k, first century, first half-ironman distance triathlon. The demands are different and you know a generic plan won’t cut it this time.

Bad race

You know you’re fitter than that result showed. Let’s find out what happened and fix it.
