Foundry Endurance Program

A more efficient way to train for endurance events.

For athletes who want to improve their time in, or complete their first marathon, half-marathon, triathlon, obstacle course race, or any other long distance event!

Foundry Endurance was developed through studying the best runners, their mechanics and training, and learning how to apply their efficiency to your running technique.  In 12 weeks, you will be able to run faster over long distances, while maintaining a strong & healthy body and decreasing your risk of injury.

We’ll utilize a combination of running workouts and CrossFit workouts to increase your speed and endurance.  In addition, weekly technique sessions will be held to improve your running efficiency and create a more natural stride.  While most endurance programs focus only on volume, Foundry endurance will prepare you to be stronger and faster and give you the confidence to finish your race and PR your time.  The program will be led by Coach Jeff Arias, who is CrossFit Endurance certified and an avid Spartan Racer.

Foundry Endurance is ideal for current or new members planning to compete in one or more races this year.  You don’t need to give up your personal life, as the program requires a reasonable time commitment of eight hours per week.  Most importantly, you’ll maintain your strength, athleticism, and physique while becoming a well-rounded endurance athlete.
