The concept is simple, at 0640 hours on Saturday, October 20, we will start a race around the 4.166667 mile Big Trail.

The time limit will be one hour.

At 0740 hours, we will begin another race around the trail.

We will do the same at 0840, 0940, and so on, every hour, until only one runner can complete a race within the time limit.

Any runner not in the starting corral for any race is not eligible to continue.

No late starts!

If no single runner can complete a race at the end, there will be no winner.

At 1840 hours, the races will transfer to a road out and back course.

At 0640 hours the following morning, we will return to the trail loop.

Have you ever thought that you could not be beaten, if only the faster runners were unable to run away and leave you? This is your chance to find out.

Every surviving runner will be tied for the lead, every hour.

All runners will receive a Backyard T-shirt.

Since the original backyard ultra was run, many replicas have been held around the world.

Most of those races have cutoffs and tiebreakers.

The Big Backyard will continue until but one man is left standing, no matter how long it takes.

This is a race to the death.

Big’s Backyard Ultra. Accept no substitutes!
