Backyard Ultra

Lincolnshire Last Person Standing Race

One Loop. One Hour. Repeat Until You Break.

Welcome to the most beautifully brutal event in our calendar. The Yellow Belly Backyard Ultra isn't just a test of speed; it is a test of the mind. Set within the stunning Area of Outstanding Natural Beauty that is the Lincolnshire Wolds, the premise is simple, but the execution is devastating.

There is no second place. There are no age category wins. In this race, there is only one Champion, and everyone else is a DNF.

How Backyard Ultras Work

The rules are non-negotiable and strictly enforced:

1. The Yard: The course is a loop measuring exactly 4.167 miles.
2. The Bell: A bell will sound on the hour, every hour.
3. The Start: You must be in the starting pen when the bell rings. If you are not in the box, you are disqualified.
4. The Lap: You must complete the loop within the hour.
5. The Rest: Whatever time you have left after finishing the loop is yours to eat, sleep, fix your feet, or question your life choices.

The race continues indefinitely until only one runner remains to complete a solo lap. That runner is the winner. Everyone else receives a "Did Not Finish."

Course

The route is 100% off-road, weaving through undulating arable farmland and rugged trails. You will be running through the grounds of Wyham, a deserted medieval village documented in the Domesday Book of 1066.

While the history is ancient, the challenge is fresh. The ground is capable of handling as many laps as you can endure, but be warned: the rolling hills of the Wolds will chip away at your legs with every yard. With over 120 Meters of elevation with each yard. This is possibly the UK's toughest Backyard Ultra
