Yellow Belly 100 Mile Ultramarathon (Spring Edition)
100 Miles. 8000ft Elevation. One continuous loop of the Lincolnshire Wolds AONB.
Yellow Belly Ultras summons you to the Yellow Belly Ultra 100 — a relentless, all‑or‑nothing odyssey across the wild heart of the Lincolnshire Wolds AONB. One loop. One hundred miles. No shortcuts. No mercy.
The route covers approximately 100 miles with about 8,000 ft (≈2,438 m) of cumulative ascent and descent and follows stretches of the Viking Way and local ridgelines and villages.
The event is scheduled for 27 March 2027. Support on course includes six fully stocked aid stations spaced along the loop. A hard cut-off of 36 hours applies to all runners.
Field size is strictly limited to 150 runners and entries are handled on a first-come, first-served basis.
Finishers who complete the course within the cut-off receive a bespoke Yellow Belly finisher’s medal and a Yellow Belly Pale Ale. Prizes are awarded to the top three male and top three female finishers.
