Ultra X 125 England takes place in the Peak District National Park, an upland area characterised by vast green landscapes, rounded hills, plateaus, valleys, limestone gorges, and gritstone escarpments.

Inhabited from the Mesolithic era, the Peak District has a rich history of agriculture, mining, and quarrying, and is now famous for its spectacular scenery, spa towns, caves, and network of footpaths and cycling trails. With a huge variety of remote terrain, challenging climbs, and stunning upland scenery on offer, the Peak District is one of the best trail running locations in the country.

Ultra X 50 England (50km single-stage race) takes place on the second day (Sunday) of Ultra X 125 England. Both races are held under full UK Athletics permit granted through the TRA.
