Fuelling is where good training goes to die — the wall at 32km, the stomach that quits at halfway, the cramp you can't explain. Bonkproof Academy fixes it, step by step, with the same methods I use as an endurance sports nutritionist with my own athletes.

None of these are a fitness problem. They're a fuelling problem — and they're fixable.
You hit the wall at the same kilometre, every race, no matter how fit you are.
Your stomach turns at 25km — bloating, nausea, a portaloo queue that costs you minutes.
You cramp in the heat and can't tell if it's fluid, sodium or pacing.
You've read five different carbs-per-hour numbers and still guess on race morning.
You carb-load for three days and still feel flat on the start line.
Every step is useful on its own. Go as far as your race needs.

Never hit the wall at 32km again.
"Four marathons, stuck at 3:45 for two years. Gene pulled up my race data and saw I was running 4:15/km through 30km then blowing up to 5:30/km. Classic under-fueling. He moved me from 30g carbs/hr to 60g/hr. Next race: 3:28, even pace."
"I hit the wall at 32km in six straight marathons. Turns out I'd been taking one gel every 45 minutes — about half what I needed. Gene rebuilt my fueling plan in grams per hour. First race after: ran the last 10K without walking."
I'm building these courses around the problems runners actually tell me about. Join the founding list and you help decide what goes in — and you get the best price I'll ever offer.
I'm Gene Convery. I've coached marathon and ultra runners for over 20 years, I'm a qualified endurance sports nutritionist, and I'm a former elite triathlete. Fuelling is the question my athletes ask me most — and the fix that most often changes their race. This is everything I teach them, in an order you can follow.
