Metabolic Testing

Our metabolic testing measures how your body produces energy across all three triathlon disciplines. By collecting VO2, VCO2, and lactate during swim, bike, and run sessions, we see exactly how your aerobic and anaerobic systems perform in real training conditions.

I am one of the few coaches in the world using a fully portable metabolic cart that allows testing directly on the pool deck, on your bike, and on the run. This gives you true sport specific data without the limitations of a lab.

I test age group athletes, international level cyclists, runners, and triathletes. The combination of gas exchange and lactate identifies your VO2max, VLamax, fat and carbohydrate usage, thresholds, and how fatigue builds in each discipline. This creates a complete metabolic profile that shows what is limiting you and how to improve.

You receive precise training zones, fueling strategies, and clear priorities for your development. Whether your goal is Kona qualification, elite cycling performance, faster run times, or improved triathlon results, this testing gives you unmatched accuracy and direction.

If you want to understand your physiology with complete clarity and train with absolute purpose, a full metabolic test is the most effective tool available.
