The St Albans Stampede is an exhilarating ultra marathon that unfolds across the picturesque Hertfordshire countryside, featuring serene stretches through Heartwood Forest and Nomansland Common. Participants have 12 hours to conquer as many four-mile loops as possible, whether solo, paired up with a partner, or joining forces in relay teams of two to eight members. The event crowns champions based on the distance covered within the time limit, rewarding top performers across three categories: male, female, and mixed. Solo runners and team participants who complete their designated laps will receive medals as recognition for their efforts. For those aiming to meet specific milestones, such as completing a marathon distance, it’s perfectly acceptable to stop after seven loops (28 miles) if they are part of the 100 Marathon Club or have other personal goals in mind. The St Albans Stampede is sanctioned by the Trail Running Association and adheres strictly to UK Athletics rules, which set age-specific limits on distances for younger runners: entrants aged 17 can run up to 25km (about 15.5 miles), while those aged 18 and 19 are allowed a maximum of 45km (approximately 28 miles). These guidelines ensure the safety and well-being of all participants. This event offers runners an unparalleled blend of scenic beauty, challenging terrain, and spirited competition as they push their limits in one of England’s most captivating landscapes.
