Run Britannia Ultramarathon
Sennen Cove, United Kingdom • 28-3 May-Jul 2027
Event Overview
Run Britannia is a fully supported multi-stage ultramarathon spanning the length of the United Kingdom from Cornwall to John O'Groats. The route covers a total distance of 1000+ miles (1609 km) with approximately 70,000 ft of elevation gain. The journey takes place over 37 days and crosses through three countries: England, Wales, and Scotland.
Course and Terrain
The route is designed to be approximately 50% off-road, utilizing several of Britain's famous long-distance paths while avoiding busy main roads. Key sections include:
- South West Coast Path
- Wye Valley Walk
- Offa’s Dyke
- Clyde Walkway
- West Highland Way (all 95 miles)
- Great Glen Way
The terrain is varied, ranging from coastal paths and moorlands to mountains and valleys. Participants encounter a mix of rocky trails, forest paths, and minor paved roads.
Logistics and Support
The event is fully inclusive, providing professionally audited safety staff, event doctors, and daily physiotherapy or massage support. Accommodation is arranged for 36 nights in a variety of settings, including hotels, B&Bs, hostels, and bunkhouses. Participants receive all meals, including breakfast at accommodation sites, evening dinners, and comprehensive "Pit Stop" services throughout each running stage.
These Pit Stops provide hydration, snacks, and medical assistance at multiple intervals daily. Support vehicles transport participants' main luggage between overnight locations, while runners carry a mandatory daypack containing essential safety kit. Navigation is managed via pre-loaded GPS files provided to each participant, as the course is not way-marked with physical signage.
