The limiting factor in races used to be my stomach, but since switching to Precision Fuel & Hydration I haven't had a single GI issue and my racing performance has significantly improved.
Caleb Olson
Pro ultrarunner
Caleb primarily enjoys trail running mountainous ultramarathons.
Growing up in the Seattle, Washington, area he loves long days in the mountains and the more technical the route, the better. He has finished on the podium of competitive international races and was 5th on his debut at the Western States 100 in 2024.
Caleb was introduced to Precision Fuel & Hydration at the 2023 World Mountain Trail Running Championships in Austria by teammate and PF&H athlete Eric LiPuma. He had been suffering from GI distress issues during races and hasn't had a single issue with that since switching over to use PF&H products. His favorite carb source is the PF 90 Gels, and he uses PH 1000 tablets for electrolytes.
When he's not in the mountains, Caleb is a software developer and loves spending time with his wife and two cats.
