The Sting Backyard Ultra is an official Backyard Ultra set in the historic market town of Richmond, North Yorkshire.
Based on the format created by Gary "Lazarus Lake" Cantrell, the challenge is brilliantly simple. Complete a 4.167-mile (6.706 km) loop every hour, on the hour. Finish within the hour and you earn the right to start the next lap. Finish early and use the remaining time to rest, refuel and prepare.
There is no finish line, no set race distance and no time limit. The event continues until only one runner can complete one more lap than every other competitor.
Whether you're taking on your first ultra, chasing a new distance personal best or simply testing your
limits, every lap is a fresh challenge. *THIS IS A COMPLETELY SELF SUFFICIENT RACE*
Please note that alcohol must not be consumed by runners whilst participating in the event.
The Sting follows the official Backyard Ultra rules.
A warning whistle is sounded at 3 minutes, 2 minutes and 1 minute before the start of every lap. When the bell rings, all remaining runners must leave together.
This isn't a race against the clock—it's a race of endurance.
The winner is the last runner to successfully complete one more lap than every other competitor. That final lap must be completed alone, with no other runners finishing alongside them.
All other participants are recorded as DNF (Did Not Finish), regardless of the incredible distance they have covered. That's simply how Backyard Ultras are scored.
If no runner is able to complete one additional lap beyond everyone else, there is officially no winner.
For your safety, all runners must have:
Your race number must be worn and clearly visible throughout the event, and your timing chip must remain attached at all times.
We also recommend bringing plenty of spare clothing, footwear, nutrition and any personal equipment you may need, as weather conditions can change throughout the event.
Non-UK Athletics Members: £100
UK Athletics Members: £98
NO REFUNDS, DEFERRALS OR TRANSFERS OUTSIDE OF WAITING LIST. We strongly recommend you take out the optional EA INSURANCE at checkout.
