Cousin Jack
Saint Just, United Kingdom • 7 Mar 2026
Cousin Jack is a challenging trail running event held in Cornwall, featuring two race options: the 18-mile Classic Jack and the 35-mile Ultra Jack. The Classic Jack is a point-to-point race from St Just to St Ives, traversing some of the most demanding and scenic parts of the coastal path, including muddy fields, rocky headlands, steep paths, and bogs. The Ultra Jack doubles the distance and elevation, starting at St Ives, heading out to Cape Cornwall, and returning, covering over 7,000 feet of ascent. Both races offer a rugged, adventurous experience along Cornwall’s stunning coastline, testing endurance and trail skills. Visit the organization's website for the most recent information.
