'Zone 2' isn't the same for everyone — and most people have never had theirs actually measured. Fat burning peaks at a specific intensity (FatMax), then drops fast. We test it directly, not estimate it. groupevolution.substack.com/…

Eat together. Laugh together. Train together. A group of like-minded athletes, an exclusive château, and Mark Allen at the centre of it all. This is what a week well spent looks like. Places available.

Same diet, same effort, different results — often not willpower, but metabolism. We test resting metabolic rate and body composition to get your actual number, not a generic estimate. groupevolution.substack.com/…
#SportsScience
Every nutrition plan rests on an unmeasured number: resting metabolic rate. Get it wrong from a formula and every calorie target inherits the error. A low measured result can flag under-fuelling early. groupevolution.substack.com/…

1/ How wrong can your wearable's VO₂max be? I compared lab tests with rest scores for 21 people. The biggest miss: a very impressive 87 in the lab vs 51.

Not a highlight reel. Real athletes — different ages, different starting points, same podium. All of them arrived not knowing exactly what they were capable of and left knowing. 2027 is the goal. The work starts now.

Most training zones come from a formula, not your physiology. We test properly — video + force data, two physiological tests that measure different things. Then we train what we find, and retest honestly. Diagnose. Intervene. Transform.

Your Garmin doesn't know your VO2 max. Your lactate test can't tell you your fat vs carb burn rate either — despite what some providers claim. The only way to get the real physiological picture: breath-by-breath gas exchange.
