       "I am extremely grateful to be a part of the team and there's a reason I have stuck with and believed in their training methods since 2004 (and continue to do so despite living in a different state). Since racing with them, I've gone from 5k runner to multiple World Championship qualifier (70.3 and IM) and I haven't had a race that I would classify as "bad," given my fitness level. Sure, there are times that I would consider "slow" compared to my potential, but that was always from a lack of fitness due to my personal endeavors and schedule. Every time I stick to the training plan and race plan, I have a good race. With the unpredictability of Ironman distance triathlons, Bettina has a remarkable track record at not only getting athletes across the finish line, but also at getting the athletes to have very strong, evenly paced Ironman races.

Thanks to Bettina's patient, logical, and smart approach to my development as an athlete, I am now preparing to race my second Ironman World Championship next month, and I can't wait to share the experience with her there!"



       "VO2 Max Testing is the best measure of an individual’s metabolism and physiology. By putting a testing patient under incremental stress loads, I am able to measure through gas exchange (Oxygen consumption, Carbon Dioxide Production) how and where the body is utilizing its fuel sources (Carbohydrate and Fat). Testing can be performed on the bicycle (stationary trainer) or running (Treadmill). Heart Rate is measured through a wireless monitor and gas exchange is measured through a facial mask that is connected to a full Metabolic Measuring Cart. As stress in increased to the body (speed increase on the treadmill, resistance increase on the bicycle) the body will use and change its fuel sources depending on intensity and fitness levels.

       I personally have tested over 4500 people in my career so far and have yet to have 2 tests come out the same. Everyone is so individualized and unique. General population charts circulate out there (Males 220-age, Females 226-age,=Max Heart Rate). These charts on based on the general population and no individual is the general population. Testing specifically tells me what is going on with an individual’s physiology and metabolism.Testing is just one component to the entire picture. It’s not just the numbers but how an individual is utilizing the numbers.


       I have been Testing Racelab athletes for many years now. Bettina and the entire crew at Racelab have been using these numbers in comprehensive training plans. It is so much fun for me to meet and test all the athletes. What a great group of people. What is even more incredible, is to see how these athletes improve their fitness levels and reach and exceed their training/racing goals. Through Bettina’s and Gus’s guidance, their athletes have an advantage. I have seen every single one of their athletes through their heart rate training plans reach levels they would have never achieved without it. These athletes are achieving the most with every workout they perform. The biggest bang for the buck. This is clearly represented in an increase in fitness, overall feeling better, recovering better, and performing better. This would not be achievable without a solid training plan. I think Bettina is one of the best coaches I know. I would recommend her /Racelab to anyone. Not only a great person, but she knows her stuff. I have hundreds of scientific testing data to prove it."

       "Racelab is not a typical training group, Racelab is an extended Family! That clearly starts with the leaders of the group. From the Coaches, Bettina, Patrick, Johann to Andy Krebs & Dave Marks….. there is a feeling of inclusion from the first interaction with each and every person involved in racelab. I’m not a “Joiner” I have always thought that the Tri Clubs, Cycling Clubs could be and would be beneficial to my training and my overall health, however just never wanted to join a group! I was convinced by Andy that it would be a good thing to check out Racelab. I joined and cannot believe what a great choice this has been for me! I have gained so much physically and mentally from my involvement with Racelab, that mere words do not begin to convey the overwhelming gratitude that I feel, each and every day. Today during swim I realized that each Racelab member inspires others in so many ways. The healthy competition that is abundant during workouts and the words of encouragement between each member for their upcoming events or training just flow in all directions. Sure, I have received top notch physical training and coaching, which is great and why I signed up, but the experiences, friendships and life coaching that I have received from Bettina has been the real benefit of my involvement in Racelab!"
