Jeff Mogavero
4th at Western States 2025
Jeff is a professional mountain ultra trail runner and loves playing outside. He competes in everything from his local hill climb to 100 mile races.
After struggling with hydration for years, Jeff got a Sweat Test in 2024. He found out he was a salty sweater, and the results fundamentally changed the way he was hydrating. Once he adjusted his electrolyte intake, he found he was able to perform much better in his 100-milers.
When not running, Jeff can be found coaching, river surfing, fly fishing, skiing, gravel biking, or adding another new hobby to the list.
When I found out I was a salty sweater, I discovered Precision to be the perfect solution to personalise my hydration and fueling needs. I used to fear fueling for 100-milers, now I look forward to it!
