First run in 1998 as the Blaythorne 10 with just 80 participants, the event quickly became a firm favourite on the Cornish racing calendar. For many years, it was known as the Storm Force 10, a challenging 10-mile race that marked the start of the Grand Prix season.
Today it has evolved into the Trevithick 12k — a shorter but equally exciting and demanding 12k race. The latest incarnation of this event was first run in 2026 and marked the start of an exciting new chapter for our club and the Cornwall Grand Prix series. Expect the usual friendly Carn Runners welcome, a fast and scenic route around Camborne, and plenty of local support along the way. Attracting over 600 runners, it proudly opens the Cornish Grand Prix Road Racing Series each year. Organised by Carn Runners, the race is the club’s annual highlight, showcasing the dedication and hard work of its members.
There will be a bespoke medal for all finishers and an optional Long Sleeved Technical Shirt is available to purchase for entries before 1st December.
