K12 Ultra Marathon & Relay
The K12 Ultra Marathon & Relay takes place at Dean Castle Country Park on 02 August 2026. The event uses an approximately 4 km circular route through the park. The course has mixed terrain, predominantly on paved paths, and includes hill sections.
The event is a 12-hour format in which winners are determined by the greatest distance covered within the allocated time. There are individual and team options. The individual event is a solo 12-hour challenge. The relay is a 12-hour team event for up to four runners per team; teams may divide the 12 hours between members in any pattern they choose.
An Athletes’ Village is provided on site with space for tented support. Competitors have access to showers, on-site toilets, a café, and boiling water. Each entry includes chip timing, a finisher’s medal, first aid cover, and marshals.
Admission for the event starts from £33. The venue is Dean Castle Country Park. The focus is on distance completed over the set duration rather than on a set distance to finish. Visit the organization's website for the most recent information.
