Ultra X England begins in Edale, a Derbyshire village bordering the Peak District National Park, taking place in September with race distances ranging from 12km to 110km. It is a trail race, offering runners choices between short, middle, ultra, and long ultra distances. September weather can be cool and variable, with average temperatures between 8°C and 18°C, making equipment selection as important as running speed.
The routes traverse Peak District ridgelines, moorland trails, and limestone valleys, utilizing the region's rolling hills rather than steep alpine ascents. The event is included in the UTMB World Circuit and is part of the broader Ultra X series, which hosts races internationally. This attracts a global field, yet the setting remains distinctly English: open moorlands, village peripheries, uneven terrain, and expansive vistas across a cherished British national park.
