The Infinity Trails Backyard are events of the Backyards Ultra calendar in France.
Created by Lazarus Lake, the organizer of the famous and mythical Barkley in Tennessee, the principle is very simple :
Because Laz wanted a loop to be made 24 times ( in 24 hours) so that it makes 100 miles ( 161 km) exactly (mythical distance in the US)
Today, the Infinity Trail circuit includes 5 official events:
Even if the numbers can scare you, Backyard ultra are accessible to everyone… Principle is simple : to do 6.7 km in less than 1 hour, so that 6.7km/h. Easy. Even if your goal is to do 3 or 5 laps, you have your place !
For example, on our Backyard in Normandy, two people stopped at 2 laps and the average of all participants is 10.2 laps, no more.
This loop format, is one of the best formats to test you on longer distances, which is close to the ultra trail. Simply to beat your distance record or run at night safely because you always come back to the base camp every hour and you are never more than 3 km from the start or finish.
Another important statistic to convince you: an amateur study was conducted in the USA on several backyards and it was shown that most of the runners managed to double their record distance ever covered on this format.
So, let yourself be tempted, you risk nothing.
It’s normal, send us a little message to tell us about it…
