St Albans Stampede - 12hr Enduro

The St Albans Stampede - 12hr Enduro is an ultra marathon held in the scenic Hertfordshire countryside, featuring parts of Heartwood Forest and Nomansland Common. Participants aim to cover the greatest distance by running multiple four-mile loops within a 12-hour period. The event accommodates solo runners, pairs, and relay teams of up to eight members.

Awards are based on distance covered, not necessarily completing the full 12 hours. The course offers a natural forest setting, and all finishers receive medals. The event is licensed by the TRA and follows UK Athletics rules, with age-related distance restrictions for younger runners. Visit the organization's website for the most recent information.
