Still hitting the wall during your long runs or rides? 🤔
The answer might be in your sweat. I turned to @precisionfandh for a sweat test to evaluate the sodium content in my sweat. The test confirmed that I am indeed a very salty sweater. Pair that with the fact that I sweat a lot, I really need to be mindful and take in at least 1000mg of sodium and at least 24 oz/hr in most conditions. Watch to see how simple this sweat test is, and head to Precision’s website to find out where you can get one done yourself.
Not taking in enough sodium can lead to cramping, elevated HR/effort based on a decrease in blood volume which can occur when sodium levels drop, brain fog or dizziness, and more broadly, bonking late in a race!
Precision F&H also does these at the races they sponsor like CIM and @boulderthon !
I got this done by @trobester at @hu.performance here in Boulder!

Big news! Boulderthon and Superganix CBD are teaming up to bring on-course Pain Relief Zones to runners this September 25-27, 2026, in Boulder, Colorado.
Inspired by an IndyCar-style pit stop, these quick-stop aid stations let runners apply Superganix’s plant-based topical Relief Balm on-course.
Check the official Boulderthon course map for aid station locations and stop by the Superganix tent at the expo or finish line to try a sample.
