What you’re in for
Eighty-one miles of the John Bunyan Trail in one loop from Bedford, 130.4km with 1,219m of climb, twenty-four hours from a six o'clock Saturday evening start in mid-September — so the first night comes early and most of the field runs through it. Runnable all the way, semi self-navigated from a GPX and the trail's own waymarkers, seven aid stations and a field of about sixty. Rural paths, villages and open countryside, and a rare chance at a long flat ultra loop in the south Midlands.
Terrain and trail
Field path, bridleway, green lane and village street across Bedfordshire, with the Chiltern edge for the only real hills. Clay, so heavy after rain, and mostly in the dark. Waymarked, GPX carried. A trail shoe.
