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.
Forged by the same crew who unleashed the Yellow Belly 50, this is its bigger, fiercer, more unforgiving sibling. A beautifully brutal pilgrimage through sweeping ridgelines, ancient Viking paths, and story-soaked Lincolnshire villages that have watched centuries of traveler's pass — but none quite like you. Every mile demands respect. Every climb contributes to a mighty 8,000 ft of ascent and descent that will test your resolve as much as your legs.
A hard 36‑hour cut-off stands between you and glory. Six fully loaded aid stations await like beacons in the night.
This isn’t just an ultra. It’s a reckoning. A challenge worthy of your ambition. A journey you’ll remember long after the finish line.
