Austin Mitchell   FastesTTransition

With background of exercise science and a niche in Triathlon, many athletes have achieved their goals with him in short sprints and Ironman distance endurence events. With experience as an elite athlete who has won multiple triathlons and who works closely with people on a one-on-one basis daily, he has learned to understand how the body responds and signs to look out for. Applying and explaining training philosophies with combination of science and athlete feedback, quickly transforms athletes.


I'm Austin Mitchell, Master Trainer, USAT LIIE coach, and High School Track Coach with over 20 certifications including NASM, and many more. Personally, I have won Multiple events overall including Wildflower, Santa Cruz, Scott Tinley, and several other events.

With over 50 events done in the past, I eventually qualified and competed in the 2016 70.3 World Championships in Australia. So I know what it takes to get to the “next level”. I coach full time and now live in Boulder Colorado where a few of the the world champions train. I work along side some of the best in the world on a daily basis, but still help many amateurs achieve their goals as well. Ive learned quite a bit about along my path to where I am today even though some may still consider me a baby in my late 20’s, but age is just a number(especially in endurance sports) If someone wants to be the best, they need to surround themselves with the best. I have trained under and alongside world champions and olympians. There are many different secrets or philosophies in training that I have come across and evolved through my own training, coaching, and reading. Im somewhat of a tri-geek, very into the data, but also am also willing to disregard science to favor the “feel” of training to get the best results because thats what separates the good from the great. If there is a triathlon book out there, I've probably read it and have a deep understanding of data analysis and the concept of periodization.
