Cousin Jack

Cousin Jack, organized by Bys Vyken Events, is a challenging trail running event held in Cornwall, UK, 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 demanding terrain including muddy fields, rocky headlands, steep paths, and bogs along the stunning coastal path. The Ultra Jack doubles the challenge, starting and finishing in St Ives, covering 35 miles with over 7,000 feet of elevation as runners head out to Cape Cornwall and back.

Both races offer a rugged, adventurous experience for trail runners seeking tough, scenic courses. Visit the organization's website for the most recent information.
