The Serpent Trail 75k Ultra Marathon

NEW FOR 2025!

The 75k is a beautiful journey through lowland heath habitats that are rarer than rainforest, ancient woodlands, coppices, greensand hills and quaint villages in some of the best, quintessentially English Countryside you could find!

The 75k/46 mile distance perfectly splits the previous options of 100k & 50k races along the Serpent Trail, as a great choice for those looking to up their distance and makes an ideal first ‘longer’ distance Ultra or brilliant distance to test yourself over and race it!

The first half of the race is slightly hillier, with most of the overall ascent in the first 30k, then it is a very flat 2nd half making it an ideal fast or first attempt at this distance - passing some of the same great checkpoints as used in the 100k and 50k races.
