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 starts with physiological testing - because you can't build a personalized plan without personal data. We measure VO2 max, metabolic thresholds, body composition, fat and carbohydrate utilization, and sweat sodium content to set your training zones, pacing targets, and fueling strategies. 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

Metabolic thresholds

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.

"I went to Tim to help me get ready for an ultra-endurance bicycle race, Race Across America (RAAM) in 2014 and later in 2016 for Race Across the West (RAW). Not discounting that I was a member of a team effort for those races, it was imperative to be ready and at my peak performance just before the races.

The bottom line is that both races were highly successful.

We crossed the 3,000 miles from Oceanside, CA to Annapolis MD in 6 1/2 days to get 4th place in our division.

And two first places in our division for RAW (Oceanside, CA to Durango, CO, 930 miles) in 2016 and 2017.2 days, 5 hours and 2 days, 3 hours respectively.

Without Tim's guidance I doubt that would have been an outcome. And I highly recommend him if you are serious about either getting in shape or training for an upcoming event."

"After completing 3 ironman events, multiple marathons and half irons, I felt pretty good and thought my fitness was optimized. However, I wanted to find out why, after pushing my training level to what I perceived to be my maximum effort, I wasn't making more progress on my fitness.

The information I obtained from the lab at Endurance has been of great benefit to my training.

With work and family commitments, ironman training used to take over the rest of my life. I'm training less now, but more efficiently, and my fitness has never been better.

Working with Endurance Team has been a life changer for me."

"Training at Endurance has revolutionized my cycling. The data driven (from my own test results in the lab) and personalized workouts make the classes the most effective 90 minutes you can spend on the bike. The results: I recently completed a double century in under 11 hours compared to riding Levi's Gran Fondo pre-Endurance in an excruciating 9 hours; my body composition has changed from 32% to 18% body fat; even my cycling technique has greatly improved - the bottom line is that 1 am having the most fun I have ever had on the bike!"
