“After my sweat test appointment I followed the plan and finally, after my strenuous work day as a firefighter followed by a Hot Pilates Class…I felt great during and most importantly after. No more post-exercise hangover!!!” - PM
What is a Sweat Sodium test?
Since 2014, Endurance PTC has partnered with Precision Fuel & Hydration to offer sweat sodium testing - one of the few places in the U.S. doing it.
The test measures how much sodium you lose in your sweat, allowing us to build a scientific, customized hydration plan just for you.

What will you walk away with?
Your sodium loss per volume of sweat
A personalized hydration strategy - how much to drink, when, and what kind of electrolyte mix you need.
Tools to adjust hydration pre‑, during, and post‑effort so you’re fueling smart, especially when conditions get tough.
Everyone loses sodium differently - what works for someone else may not work for you. Standard “general” hydration advice can miss the mark.
Proper hydration isn’t just about comfort; it’s about performance, recovery, avoiding heat illness, cramps, and feeling good in and between workouts.
Having precise data means fewer guesswork days, better training consistency, and more confidence when pushing limits.
Why is all of this important?
Athletes (any level) who want to optimize performance.
Anyone training or competing in heat, humidity, or for long durations.
Individuals who struggle when exercising in hot or humid environments, where proper hydration is crucial for healing.

“We've worked in partnership with Tim and EPTC for many years and it remains one of the most positive business relationships we've established through Precision Fuel & Hydration. Tim has a blend of academic experience in Sports Science and practical know-how from his own athletic exploits and we've always had fantastic feedback when referring athletes to him for help with their training, fueling and hydration strategies. Tim's also just a genuinely warm and friendly individual and hanging out with him in Mill Valley has been a real highlight in our many trips to the Bay Area over the years.” - Andy Blow, Founder/CEO, Precision Fuel & Hydration
