Four Peaks of Ireland: End-to-End

​Name: Four Peaks of Ireland: End-to-End
Start: Slieve Donard Trailhead, Newcastle, Co. Down 
Finish: Carrauntoohil, Co. Kerry
Length:  567 Miles/ 912KM
GPX: Link​​ and file

Description:    This is a fully continuous north-to-south crossing of Ireland, linking the country’s four provincial high points entirely by bike and foot. No transfers, no shortcuts, no resets. Just human-powered movement from the first step on Slieve Donard to the final descent off Carrauntoohil.

Riders will encounter:
  • 4 mountain ascents
  • 3 ultra-distance cycling legs
  • Mixed terrain, overnight riding, and multi-day endurance effort
The route combines endurance cycling, mountain hiking, sleep management, navigation, and resilience into one continuous challenge.This route feels genuinely special because it combines almost everything that makes endurance adventures memorable: huge landscapes, sleep deprivation, changing terrain, long night riding, remote climbs, and the feeling of crossing an entire country under your own power.
What makes it compelling is not just the physical challenge, but the flow of the journey itself. You begin beside the Irish Sea in County Down, move through the Wicklow Mountains, cross the Midlands through the night, reach the wild Atlantic landscape of Mayo, and finally finish deep in Kerry beneath Ireland’s highest mountain. Every stage feels different physically, mentally, and visually.
We’ve intentionally designed the effort to remain fully continuous and FKT-compliant while still prioritising safety, teamwork, and sustainable execution over chasing arbitrary time splits. The challenge is ambitious enough to feel almost unreasonable, yet achievable with the right preparation, discipline, and team dynamic.
Most importantly, this is the kind of route that people will remember long after the finish. It has the ingredients of a proper adventure: uncertainty, exhaustion, incredible scenery, shared suffering, and the rare feeling of doing something that may genuinely not have been done before.
