Same hour. Different ground. Run a backyard ultra wherever you are, on the same bell as everybody else, and watch the whole corral hour by hour.
A backyard ultra is not a distance. It is a shared hour and a binary outcome. THE YARD keeps the hour: you run on your own ground, you start when everybody starts, and you are out when the clock says you are out.
Register for an event, then set up your entry here with the email you registered with. Registration alone does not put you in the corral.
Every hour, on the hour, run 4.167 miles or more on any ground you choose. Road, trail, track or treadmill.
Upload the GPS file from your watch. The timestamps decide which loop it is, and your row in the corral fills in.
Saturday, December 19, 2026. First bell 8:00 AM Central. One 4.167 mile loop every hour, up to 24 loops and 100.008 miles. Fourteen of the twenty four hours are dark.
Whatever happens in the yard, there is a real corral waiting. The Last Frontier Circuit, in person, in Texas.
