November Nightmare 8 Marathons In 8 Days 2026

November Nightmare is an eight-day running series in Telford, Shropshire, held in early November. Each day offers runners a choice of 8 miles, a marathon, or a 16-mile option, making even the middle distance more challenging than it sounds. Runners can enter one day, a few days, or attempt all eight, which explains the series' name. The event is organised by How Hard Can It Be Events, and its format suits those seeking repeated long runs over a single race effort.
