On August 28, 2027, runners from all walks of life will gather for the Backyard Ultra, an endurance challenge that tests both physical and mental limits. The race begins at 9:00 AM with a simple yet daunting concept: complete one lap of 4.167 miles every hour on the hour. Participants start their laps precisely when each new hour begins and have exactly sixty minutes to finish them. Once completed, runners are free to rest, refuel, or prepare for the next round until they're ready to face another mile-long loop. The race continues in this fashion, with everyone running until just one person remains standing. This format is as much a battle against oneself as it is against others. There's no pressure to reach any set distance; instead, runners are encouraged to see how far they can go without exceeding their personal limits. Over the past five years, participants have achieved remarkable milestones such as completing their first half marathon or even reaching 100 miles. The current event record stands at an impressive 32 laps held by Terry Smith. This year, competitors will aim not only to break this mark but also to claim victory in a unique team challenge. Teams of six runners start together and continue until each member has reached their limit. Each lap completed counts towards the overall score for that group. In recent years, East Cornwall Harriers have dominated the team competition with impressive total laps. This year's event promises to be an exciting battle as new teams look to unseat them from the top spot. Whether you're a seasoned runner or just looking for some fun and camaraderie, forming your own six-person squad could lead to bragging rights for weeks. The weekend also includes a special mini Backyard Ultra on Friday evening, offering both individuals and support crews an opportunity to participate in either one or two laps before the main event. This relaxed setting allows everyone—from seasoned athletes to casual runners—to enjoy some friendly competition without feeling pressured about performance. All funds raised from entries go directly toward supporting people living with Bowel Cancer as well as funding vital research and training initiatives. By participating, you're not only testing your own endurance but also making a significant impact on the lives of those affected by this serious disease. Don't miss out on the chance to join in one of the most exhilarating running events of the year! Sign up now through our website and prepare for an unforgettable weekend filled with challenges, camaraderie, and personal achievement.
