Kent Backyard Ultra Series 2 Vigo is a last-runner-standing Backyard Ultra held at Vigo Rugby Club in Kent, near Luddesdown. It begins at 9:00pm, with participants completing the same 4.167-mile loop each hour on the hour. All runners start each loop simultaneously; no one may depart early. The event continues until only one runner remains or all others miss the hourly deadline.
The course combines trail paths, rural sections, and consistent gradients, requiring measured pacing alongside pure endurance. Runners are self-supported between laps, utilizing the brief interval after each loop for refueling, changing gear, and preparing for the subsequent start. This event is part of the Hellfire Backyard Ultra series, and the total distance achieved is determined by the number of hourly loops a runner successfully completes.
