“The bike fit with Andrew at Endurance gave me the confidence and comfort to get back into shape for my cycling season after suffering a broken hip. During the bike fit, Andrew explained every detail of what he was changing on my old fit and why it would impact my cycling for the better. He asked me what I thought we needed to focus on in the fit. Which for me was my cleat position as well as pedaling style and he made it perfect. After, Andrew dove into every aspect of the fit and shaped everything around my riding style. Following my time at endurance I feel much more comfortable on the bike, which was much needed after my injury. I’m extremely appreciative to the team at Endurance for giving me the much-needed support to get back into high-intensive training and criterium racing.”

“I did the Elite Performance Assessment with Tim Flemming here at Endurance PTC. As a professional triathlete, I needed to know where I was at the start of the 2023 season and, in keeping up with industry standards within the elite field, knowing to what extent I produce and clear lactate at different efforts was the obvious path to improvement.

I expected a ramp test on the bike and run with a few ear pricks and 3 customized zones with which to move forward. I was pleasantly surprised at the extent of insight working with Tim. After the first day of testing we sat down for an in-depth review of the data as Tim helped illuminate concepts, understanding and strategy. The focus shifted from "what are my numbers," to an all encompassing understanding of my body composition, how energy systems work and how I can optimize how much body uses fat, carbohydrate and oxygen as energy to yield gains as high as 10%. As an older pro who thought my job was to prevent decline as long as possible, this was super encouraging.

And the strategies are different for the bike and the run because the energy systems operate differently for me in these two disciplines at this time. Both would take a pretty focused and committed 6-8 week program to yield adaptation. As such, Tim made himself and his knowledge available to my coach and I so as to ensure we put together the optimized 6-8 week plan, which was a little different than what we were planning but we saw the data and analysis, and all agreed this is the path forward.

Four weeks into this plan, I'm stronger on the bike and just set some personal bests on the run.

I would recommend this testing protocol for anyone, not just pros, looking to improve their performance and/or enjoy their past times as healthy as possible.”

“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.”

“WISH I DISCOVERED THIS PLACE 10 YEARS AGO! I grew up in Mill Valley but didn't discover this hidden gem until 20 years later... Why is Endurance PTC a hidden gem? For starters, they offer EVERYTHING you need to reach your goals as an high-performance athlete, recreational fitness enthusiast, or anything in between. So far, I've gotten sweat tested (to find out my sweat sodium concentration), my body healed by Tim with neuro-kinetic therapy – helping me realize I wasn't activating the right muscles while riding bike which was leading me down a dangerous road to inevitable injury. The difference was immediately noticeable and carried me through my first professional triathlon 2 weeks later. I also got a bike fit from Andrew. This guy brings in 15+ years of experience and it definitely shows. He's deliberate, friendly, and considered my opinion throughout the process – truly only wants the best for his clients. I plan to consistently follow up with both Tim and Andrew and dig into everything else EPTC has to offer, including metabolic testing to uncover how to optimize my training. As someone who's been through every phase of being an athlete (beginner to professional), I wish I discovered this place 10 years ago!”

“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.”

"I have done performance and submaximal testing - as well as eCycling classes - with Tim over the last few years and highly recommend Tim and Endurance PTC for athletes at any level. The testing protocols and equipment are state-of-art and the programs are delivered with consummate professionalism. I have been particularly impressed by Tim's knowledge of exercise physiology: its rare to find an athlete who has competed at the highest levels as Tim has and then applied themselves to understanding the scientific principles of exercise physiology. Tim has helped me stay motivated with my training and at the same time optimize the specific components of my training plan. Finally, he delivers all that with a smile and an inspirational attitude!"

"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 I am having the most fun I have ever had on the bike!"

"It's common knowledge that performance testing is a great way to gauge your fitness, and there are many labs that can churn out some numbers and give a snapshot of where you stand. But the key to maximizing your potential as an athlete comes from understanding that data and applying the lessons learned to your training. This is what sets Endurance apart from all the rest. Tim's deep knowledge of physiology and cycling is incredible. He has an uncanny ability to thoroughly yet succinctly explain testing results and work with each athlete to maximize their potential." –

Phil Mooney, retired professional cyclist and director of Voler Apparel Factory Racing.

“When I joined Endurance three years ago, I was an aging “weekend warrior” simply looking for variety in my workout regimen. Tim then introduced me to the benefits of incorporating their lab science into my training, which took my fitness to a new level. Last summer, he used my testing data to design a training program that enabled me to enjoy the Death Ride…seriously. This weekend I rode in the Levi Gran Fondo. To say that I am a big fan of Endurance would be an understatement.”

“The testing process was straightforward, easy to execute and easy to understand. I left with relevant numbers, and specific, actionable training recommendations based on my test results. leaving with specific training recommendations was a huge plus, many testing protocols simply spit out physiologic data.”

Hi Tim,

“It's always good to start your Monday with a positive email. You mentioned that my results showed that we may have found the "Silver Bullet"…you were right!!!!! After my sweat test appointment I followed the plan and finally, after my strenuous work day as a firefighter followed by a Hot Pilates Class… I felt great during and most importantly after. No more post-exercise hangover!!!”

Thank you,

“Very pro. Very detailed. Went in for custom footbeds and ended up discussing much more about my fit and my saddle issues. Sat on the digital sit-bone scanner and learned that my saddle was way too narrow. Anthony gave me a loner to try out on the road! I am super grateful.”
