BigMud Trails (EARTH) 2027

BigMud is the Earth race in the Classic Element Trail Series, a collection of four trail events themed around Earth, Water, Fire, and Air. It starts at Queen Elizabeth Country Park in Hampshire, offering three single-lap options: a 50K ultramarathon, a marathon, and a 16-mile race. The event occurs early in the series, embracing muddy winter trail running over road speed or flat pacing. The routes venture into the Meon Valley and traverse the rolling hills of the South Downs National Park. Every distance involves the 518ft ascent to Butser Hill, the highest point in the South Downs, which runners climb twice before returning to Queen Elizabeth Country Park at the hill's base. The race is in its sixth year, does not permit canicross entries, and requires each runner to carry a minimum of 500ml of fluid, with hydration vests frequently used and handheld soft flasks permitted.
