Nav4 Tour de Helvellyn
Askham, United Kingdom • 20 Dec 2025
The NAV4 Tour de Helvellyn is a challenging winter ultra running event held in the Lake District, starting and finishing at Askham. Covering approximately 38 miles with around 2000 meters of ascent and descent, the route circles Helvellyn via mountain trails, bridleways, and minor lanes, reaching heights near 600 meters. This unmarked course demands strong navigational skills, winter hill running experience, and self-reliance, as support is minimal and individual crews or pacing are not permitted. Limited to about 200 experienced entrants, the event emphasizes safety with strict kit requirements including waterproofs, thermal layers, navigation tools, and emergency gear. The atmosphere is low-key and focused on winter mountain skills, with refreshments like tea and soup provided at the finish. Visit the organization's website for the most recent information.
