FTP tells you your ceiling. Lactate tells you how to raise it. Find the training zones that build endurance, speed recovery, and drive adaptation.

BIOWEAR PERFORMANCE LAB · SAN DIEGO
Lactate testing for cyclists, triathletes, and HYROX athletes
Limited time offer through September 30th
Why lactate
Blood lactate is the reference method for setting training zones. Professional teams and national federations use it because it is the only way to know where an individual athlete's thresholds actually sit.
Everyone else is estimating. Two athletes with the same max heart rate can be thirty watts apart at the same effort — one building an aerobic base, the other just collecting fatigue.
Same max heart rate · Different threshold
Athlete A
Max HR
190 bpm
LT2
265 W
Training at 240 W builds an aerobic base.
Athlete B
Max HR
190 bpm
LT2
235 W
Training at 240 W just collects fatigue.

FTP tells you your ceiling. Lactate tells you how to raise it. Find the training zones that build endurance, speed recovery, and drive adaptation.

Stop guessing your race pace. Identify the highest effort you can sustain and still run strong off the bike.

Better pacing. Faster recovery. Stronger finish. Learn where fatigue takes over and train to push that line higher.
What you get
Your two thresholds. LT1 and LT2 in watts, split, and heart rate, each confirmed by three independent methods rather than one formula.
Training zones anchored to those thresholds. Based on your actual physiology, not a percentage of max heart rate.
Your lactate curve, and the gap inside it. The distance between your two thresholds is the most useful number in the test. A wide gap means you are ready for intensity. A narrow one means your base comes first.
Blood glucose at every stage. Drawn alongside every lactate sample. It shows how you fuel the work, where your body changes strategy, and whether you arrived properly fed.
How quickly you recover. Samples after you stop show how fast lactate leaves your blood. It tends to improve with aerobic training sooner than your threshold does, so on a retest it is often where you see the work paying off first.
A plan to move your threshold. Which zone to live in, how much time to spend above it, and what to change first, against the goals you came in with.
Delivered as a written report 48 hours after your test, with an optional call to walk through it.
