ADRIAN · IRONMAN HAMBURG, JUNE 2026One triathlon athlete. His own numbers.

  • 60 → 100 g/hGUT TOLERANCE, 9 WEEKS
  • 42 KM, ONE PACENO FADE · STANDALONE MARATHON
  • NO GUT ISSUES8 weeks out → RACE DAY
How many gels for the 3h run?
Can you tell the amount of powder for 800 and 500ml?
From 3:11h I felt tired
My 6h ride costs 40-50€ in gels. And the powder mixing is so easy to mess up.

A six-hour ride creates dozens of tiny decisions.

You shouldn’t be doing maths mid-ride.

THE FUEL PLAN

Every session, packed and timed.

  1. BEFORE THE RACE

    At 30 km others start slowing, slipping into survival mode. That moment doesn’t reward effort — it exposes who fuelled properly and who didn’t.

  2. AFTER

    Like you said at km30 I only overtook the people

  3. Didn’t even push all out

Adrian’s own splits — a standalone marathon, not the IRONMAN run leg.

Most athletes pick a ditch.

OverfeedFast recovery, but end up gaining fat.
UnderfeedSluggish recovery, and low energy.
Fed properlyWeight is maintained or slowly getting leaner. Recovery is optimal, energy is consistent.

GUT CAPACITY

“I have to hit 800 g of carbs today — but I can’t eat that much rice and pasta in one sitting.”
  • CAPPEDEvery sitting stays finishable. No gut irritation.
  • REAL FOODDrinks are a tool, never the plan. They make a gut lazy.

Real food, split across the day. That’s what trains a gut to 100 g/h.
