Metabolic Testing
Unlock Your Performance Potential with Metabolic Testing
Delivered by Tri Coach Jon – Trusted by Champions, Grounded in Science
Whether you’re chasing an Ironman PB, training for your first marathon, or simply tired of training on guesswork, true progress begins with real data. At Tri Coach Jon, we go deeper — beyond pace, beyond heart rate — into the physiology that fuels performance.
What We Test
- VO₂ Max – Discover your true aerobic capacity
- Lactate Threshold (LT1 & LT2) – Nail your training zones with confidence
- FatMax – Pinpoint where your body burns the most fat for fuel
- Carbohydrate Burn Rate (CHO g/min) – Calculate exact fuelling needs for race day
- Resting Metabolic Rate (RMR) – The foundation for fat loss and recovery nutrition
- Sweat Rate & Sodium Loss (FlowBio) – Custom hydration that works with your physiology, not against it
- Muscle Oxygen Saturation (Train.Red Sensor) – A cutting-edge look at how your muscles use oxygen in real time during training or testing
Your Data. Your Performance.
You’ll walk away with lab-grade insights and an actionable plan. Every test includes personalised recommendations — whether for fine-tuning your current training or as the basis for a fully-coached programme.
Who This Is For
- Coached athletes who want precision data to enhance their plans
- Self-trained athletes ready to train smarter, not just harder
- First-timers and elites alike who want to make every session count
