IRONMAN · TRIATHLON FUELLING

Just tell me what to do.

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.

  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.

Your race target isn’t guessed on race week.

Most athletes pick a ditch.

OverfeedTrain harder than ever. Gain fat anyway.
UnderfeedNever recover. Flat, tired, stalled.
HELDFuelled it. Didn’t overshoot.

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.

COST
