The Ultra:5K returns to Box End Park on July 13, 2025, offering a fresh twist on traditional racing with two options: the Ultra:5K THREE, where runners complete 3 x 5K races from 11:00 AM, and the Ultra:5K FIVE, a 5 x 5K challenge beginning at 9:00 AM. In each format, runners must start a new 5K on the hour, giving them only the remaining time of each hour to rest before the next start. The scenic, traffic-free course at Box End Park makes the event accessible yet challenging, demanding strategy, pacing, and resilience. All participants receive a bespoke finisher’s medal, full support with hydration and nutrition, and access to massage and recovery zones. With capped entries and a high-energy atmosphere, the Ultra:5K delivers a unique racing experience designed for those who love short distance with an endurance twist.
