Tsunami Ocean Trails

Bude, United Kingdom • 6 Jun 2026

TSUNAMI Ocean Trails is OuterEdge Events’ rugged coastal trail challenge along the North Devon and Cornish coastline. The Ultra-marathon runs 37 miles from Westward Ho! to Bude; the Marathon goes from Clovelly harbour to Castle Bude; the Sixteen-mile option runs Hartland Quay to Bude. The courses traverse wild, remote cliff paths with almost 2,000 metres of ascent, and are deliberately isolated with few towns along the way.

It’s described as a tidal wave of endurance trail running. Finishes are at Castle Bude, starting points include Clovelly harbour (Marathon) and Hartland Quay (Sixteen). Features include fully marked routes, on-course first aid, bespoke Tsunami medals, and optional bus transport to starts. Visit the organization's website for the most recent information.
