One test. Everything your watch guesses: VO2 max, real training zones, thresholds and how you burn fuel. On the treadmill or your own bike.
You breathe into a mask while the pace climbs, and we measure every breath. When you’re done, you know exactly what your engine can do and how to train it.
What you get
VO2 max, measured instead of estimated
Heart rate and pace/power zones built from your own breathing
Aerobic and anaerobic thresholds
Your fat-to-carb crossover
Carbs and calories per hour at race pace
A results report you’ll actually understand, plus a walkthrough
How to prep: Eat normally, skip hard training the day before, wear what you train in, and skip caffeine for a few hours before.
Want the full picture? Pair it with the Sweat Test in the Baseline for $349.
