Carrauntoohil Ascents

First

In Ireland

Ten ascents. One mountain. A single unbroken window of 24 hours. Carrauntoohil is Ireland's highest peak — steep, exposed, and unforgiving. Repeating it ten times back-to-back meant negotiating night navigation, shifting conditions, and relentless fatigue. The result: a first for Ireland — 10,000m of vertical inside a day.

What It Took

  • Meticulous route planning and night navigation
  • Support crew coordination through the small hours
  • Nutrition and pacing strategy engineered for 24 continuous hours
  • Weather windows that could not be predicted, only accepted

Key Lessons

  • Break the impossible into repeatable units — then trust the process
  • Mental discipline outlasts physical strength
  • Fatigue lies. Systems and preparation tell the truth
