Sarah Humble
Elite Ultrarunner
Sarah specialises in trail ultramarathon running, but she loves all forms of running.
Sarah won her debut 100 miler at the Bear 100 in 2025 and placed 4th at Canyons 100k in 2026, which earned her a golden ticket into Western States.
Growing up at the base of the Wasatch Mountains and currently living in Salt Lake City, Utah, she was introduced to Precision Fuel & Hydration just as she started taking her running more seriously. After the combination of a Precision Sweat Test and easy-to-dial-in products helped her manage some nutrition issues, she was hooked.
Catch Sarah exclaiming how beautiful the wildflowers are, rolling out her feet under her desk at her tech job, and enjoying the darkest chocolate she can find.
My running has been transformed since joining PF&H. I've gone from no fuel, to fueling with homemade beet and rice, to now Precision Fuel & Hydration. It's not a coincidence - Precision is just so much simpler and more effective.
