Have an Endurance Science Labs coach run your test.
If you're in the Boulder or Denver area, an Endurance Science Labs coach
can run the full sprint + step-test protocol with you in person. We
bring the meter, the strips, the cooling, and the experience to make
sure the numbers are clean — and we walk you through your results.
What's included
◆ Equipment provided
Lactate meter, strips, lancets, alcohol prep, gauze, fan — you just bring yourself and your bike or running shoes.
◈ Sprint lactate test
15-second all-out sprint with blood samples before and after, catching the peak window most home protocols miss.
◉ Lactate Step Test
Full 5-minute-stage step test on your bike or a treadmill — we handle the timing, sampling, and stage cues while you focus on the effort.
⬡ Profile walk-through
Your VO₂max, sustainable threshold, easy-zone limit, fat-burning sweet spot, and personal training zones — explained in plain language with training implications.
Sessions run about 90 minutes including warm-up, both tests, and the
results walk-through. Bring a snack and water for after.
What you walk away with
A full metabolic profile — the same picture lab-grade commercial tests cost coaches several hundred dollars to produce. Built entirely from your own data, not a population average.
◆ Race-pace targets
A number you can hold — for the half-marathon, the half-Ironman, or an all-out hour effort — derived from where your body just keeps up with the lactate you produce.
◈ Custom training zones
Training zones for cycling, running, and base-building — built entirely from your own data, ready to paste into your training app.
▶ Carb fueling targets
How many grams of carbs you burn at every intensity — so you know exactly what to eat on long runs, race day, and tempo sessions before you bonk.
⬡ Your fat-burning sweet spot
The pace where you burn fat fastest. The foundation of every aerobic-base block, and the intensity you can hold for hours.
