What is a Backyard Ultra? (Short definition)
A backyard ultra is an ultramarathon format in which a 6.706 km lap is started every hour. Anyone who does not finish a lap within 60 minutes or does not arrive in time for the next lap is eliminated. The winner is the last person to complete another full lap.
There is no fixed total distance - only one winner.
Why exactly 6.706 kilometers?
The distance is exactly 4.167 miles.
After 24 laps, there are exactly 100 miles (160.9 km) - a classic ultramarathon mark.
However, in the Backyard Ultra, this is usually only an intermediate goal. Many races last:
36 hours
48 hours
60 hours
or longer
International records are now well over 100 laps - in other words, more than 670 kilometers.
Official rules for the Last Man Standing race
The rules are minimalist - but uncompromising:
Each lap must be completed in its entirety within 60 minutes
Whoever is not at the start on time on the next full hour, is eliminated
The course may only be left after a lap has been completed
There is only one official winner
All others are considered DNF
In contrast to classic ultramarathons, there are no rankings for second or third place.
Backyard Ultra vs. 24-hour run: the difference
Many people confuse the two formats. The differences are fundamental:
24-hour-Run | Backyard Ultra |
|---|---|
Fixed duration | Open end |
Distance decides | Stamina decides |
Multiple winning classes | Only one winner |
Even pace | Hourly rhythm |
Target time in focus | Survival principle |
The decisive factor is psychological uncertainty.
Nobody knows how long the race will take.
How many kilometers do you run in the Backyard Ultra?
The distance depends solely on the number of laps completed:
10 laps = 67.06 km
24 laps = 160.9 km (100 miles)
50 laps = 335.3 km
75 laps = 502.9 km
100 laps = 670.6 km
The longer several athletes last, the longer the race takes.

Backyard ultra training: how to prepare yourself optimally
When people search for "backyard ultra training for beginners", they often think of speed. But speed is secondary.
1. Basic aerobic endurance (zone 2)
Long runs in the low intensity range improve your fat metabolism capacity and running economy. The aim is to run economically for many hours.
2. Simulate an hourly rhythm
Training principle:
Start a moderate session every 60 minutes to internalize the competition rhythm.
3. Test nutrition
Backyard Ultras place high demands on stomach tolerance.
The following should be tested:
4. Develop mental strategies
Studies on endurance performance show that self-regulation, attention control and emotion control are crucial. Visualization and structured routines help to delay mental fatigue.
Strategy for the Backyard Ultra: How to last longer
Don't start too fast
Experienced athletes often run between 6:15-6:45 min/km.
Constancy beats speed
Even lap times reduce energy loss.
Use breaks strategically
10-20 minutes between laps is crucial for:
energy intake
hydration
mental stabilization
Crew support
Structured support can optimize organization and recovery.
Mental strength in extreme endurance running
The Backyard Ultra reduces the stress to a single question:
One more lap?
This psychological reduction makes extreme distances manageable. Research on mental fatigue shows that cognitive fatigue often sets in before muscular fatigue. Strategies for self-regulation can therefore be decisive for performance.
The Backyard Ultra is therefore a physical and cognitive competition at the same time.
Equipment for a Backyard Ultra
