Race Description

Yellow Belly 50 Mile Ultramarathon (Summer Edition)

50 Miles. 4,500ft Elevation. The Wolds at their finest.

Experience the Lincolnshire Wolds in all their glory. The Yellow Belly Ultra 50 is a stunning circular tour of one of the UK’s most underrated landscapes. Forget the myth that Lincolnshire is flat; this route packs a punchy 1,370m (4,500ft) of elevation as it weaves through historic villages, rolling arable farmland, and scenic sections of the famous Viking Way.

Whether you are hunting for a fast time on firm ground or looking to pop your 50-mile cherry, this is the race for you.


The Race Format

We have designed this event to be accessible yet challenging. With a generous 18 hour hard cut-off, this is the ideal entry point for aspiring ultra runners taking on the 50 mile distance for the first time. For the seasoned endurance athlete, the rolling terrain offers a chance to push the pace and clock a serious time.

  • Distance: 50 Miles (Circular Loop)
  • Elevation: ~1,370m (4,500ft)
  • Support: 4 Fully Stocked Aid Stations

Registration & Kit Check: To ensure a stress-free start, we strongly urge all runners to register the evening before.

Capacity: Strictly limited to 150 runners. We operate on a first-come, first-served basis. Once the 150 spots are filled, entries will close.

Note: Parking at Swallow Village is extremely limited. We ask all runners to car share where possible to reduce congestion.


Awards & Prizes

It’s not just about the glory; it’s about the hardware.

  • Finishers: All runners who complete the course within the 18-hour limit will receive a bespoke Yellow Belly finisher’s medal.
  • Podiums: Prizes will be awarded to the 1st, 2nd, and 3rd place Male and Female finishers.

Why Run the Yellow Belly 50?

This isn't just a run; it's a tour of the county's hidden gems. You’ll experience the camaraderie of the trail, the support of our dedicated volunteer team, and the satisfaction of conquering the Wolds.

Prepare for the hills. Enjoy the views. Earn the medal.
