Cousin Jack

Cousin Jack, organized by Bys Vyken Events, is a challenging trail running event held in Cornwall, UK, featuring two race options: the Classic Jack and the Ultra Jack. The Classic Jack is an 18-mile point-to-point race from St Just to St Ives, traversing rugged coastal terrain with muddy fields, rocky headlands, steep paths, and bogs. The Ultra Jack doubles this challenge with a 35-mile out-and-back course from St Ives to Cape Cornwall and back, featuring over 7,000 feet of elevation.

Both races offer a tough but rewarding experience along one of Cornwall’s most stunning and demanding coastal paths, promising an unforgettable adventure for trail runners. Visit the organization's website for the most recent information.
