Ultrarunner Ray Sanchez Speaks Out!

Ultrarunner Ray Sanchez sees Success with Marc Pro

I have personally been impacted by the value of your product. Having just completed a run from Chicago to California in 17 days with 7 of my closest friends, I know our success hinged on the Marc Pro product and technology.

Having completed more than 135 ultra races on 3 continents in the last 5 years, I can attest my only regret was that I didn’t have access to you sooner.

Thank you MarcPro! I have lifelong loyalty to you!
