About this race
The North Chilterns 50K is a 50K ultramarathon east of Luton, starting early Saturday morning in November. It is a trail race, focusing on ridge running, open ground, and extensive views across the Chilterns.
The course follows ridgeline trails in the North Chilterns, offering a countryside ultra with significant exposed high ground, unlike a flat city route. Runaway Adventures Limited organises the event, with entries at £65. UK Athletics club members receive a discount.
