The Western States Endurance Run (WSER) is an iconic fixture in the world of ultrarunning. As the world’s oldest 100 miler, it has become a symbolic representation of the ultimate endurance challenge. Few people have as much knowledge about Western States as my guest today, Andy Jones-Wilkins. Andy has completed Western States an incredible 10 times, along with other 100 milers such as Hardrock, Leadville, Wasatch and Vermont.

Invented by renowned physical therapist Jay Dicharry, MOBO helps you stabilize your stance with an innovative rocker board that’s set up on two fins. The design effectively forces you to drive your big toe into the bboard to improve your stability. I was pretty arrogant going into my first session on the MOBO Board. How hard can it be to balance, right? Well, I was humbled pretty quickly! Even if you’re a good runner, better balance, stability, and proprioception is going to help you have a more powerful stride and prevent more running injuries. You’ll learn how to improve the efficiency of the kinetic chain from your hip to your big toe. Because as Jay likes to say, it’s not just how strong you are, but how well you use that strength. I was just at a weekend physical therapy workshop (lol I was the only running coach) and learned how important (and rare) this simple movement is.
