A data-driven approach to endurance training

Join our team to improve your performance, breakthrough plateaus and increase the size of your aerobic engine!

What Makes Us Different?

All of our training sessions are based on data. You will undergo extensive testing to determine your current aerobic fitness which will allow you to train at the exact intensity and duration to improve your performance.

“If you can’t test it, you can’t improve it.”

Our goal is to target your weaknesses and enhance your strengths. During onboarding we will test your Anaerobic Power, Functional Lactate Threshold, Functional Threshold Power (FTP) and Heart Rate to determine your training zones. This allows us to prescribe workouts and assign precise pacing specific to your needs.

Are You Training With Purpose?

Most athletes start a crossfit WOD, hop on their bike, jump in the pool or head out for a run without a predetermined pace, intensity or intention. This often leads to plateaus in training, increases their risk of injury and prevents them from reaching their full athletic potential. 

At Pure Endurance, we believe that data is vital to improving your aerobic capacity. We have developed a system that utilizes a variety of training metrics which individualizes each workout based on your current fitness level. We believe that understanding the science of endurance training is vital in helping athletes of all levels achieve their goals.

What Are Your Weaknesses? ⁠

If running is your weakness and your box only programs running two times per month you will never get better at running. This can be said for rowing, biking, and swimming as well. ⁠

If squatting is a weakness for you and you want a stronger squat, what do you do? You Squat on a specific program with specific reps and percentages!⁠

If you want to make your weaknesses your strengths you must specifically target them. It is hard to build your aerobic engine without following a program.⁠
