About UK Sea to Summit 3 Peaks Trilogy

The UK Sea to Summit 3 Peaks Trilogy comprises three separate ultramarathon-distance trail races, each ascending a major British peak from the coastline. Taking place between early September and early October 2026, the trilogy visits Scafell Pike in England's Lake District (28 miles), Snowdon in Wales (29 miles), and Ben Nevis in Scotland (31 miles), with each challenge held on a different date.

The routes are specially designed trail and country paths leading from the coast to each summit, fully way-marked and supported throughout with safety crews and pit stops. Runners can enter individual peaks or tackle all three for the complete trilogy experience.
