How the Backyard Ultra format works
Learn how to plan a repeatable hour, then choose a race that fits.
The format in brief
A standard Backyard Ultra starts a new 6.7056 km (4 miles 880 feet) loop every hour. You must finish inside the hour and be in the corral at the bell. If you miss a start, you are out. Local events may use capped or adapted rules, so check the organiser's current rules.
Choose a race that fits
Compare the surface, elevation, weather, facilities, entry process and format. Use country filters and the catalogue to browse; confirm registration and current rules with the official organiser.
Crew and camp planning
Plan what you need between loops: food and drink you have practised, layers, lights, foot care and a simple reset routine. Check what the event allows for assistance and equipment.
Plan the hour
The table is illustrative, not a target. It shows the total time for one 6.7056 km loop, including stops, and the time left before the next hourly start.
| Illustrative loop | Average pace | Rest before next start |
|---|---|---|
| 45 min | 6:43 / km | 15 min |
| 50 min | 7:27 / km | 10 min |
| 55 min | 8:12 / km | 5 min |

Backyard Ultra FAQ
How far is one Backyard loop?
The standard loop is 6.7056 km, or 4 miles 880 feet (4.166667 miles). Events can vary, so check the organiser's rules.
How is the winner decided?
The winner must complete one more solo loop than every other runner. If no one completes that extra loop, the standard rules record no winner. Local formats may differ.
Is Backyard Ultra suitable for beginners?
There is no universal entry requirement or guaranteed mileage. Assess your current base, choose a suitable capped or shorter-format event if offered, and read its rules before entering.
How do I enter a Backyard Ultra?
Use the official registration link for the event. Confirm the date, cap, location, entry conditions and current rules with the organiser.
