With the urging of Gary Cantrell, aka Lazarus Lake, aka Laz, who started the original Big Dog’s Backyard Ultra and the Barkley Marathons, more races of this layout are being started. This is one of them. So in likewise fashion, the Ohio Backyard Ultra will follow as closely to Laz’s original format as possible. The concept is simple. It’s a “Last Person Standing Race” and in the end, just one runner will finish the race.

At 0730 hours on Saturday, March 23, we will start a race at McChesney Ridge around the Ten-Bridge Trail for 4.1667 miles. The time limit for this race is one hour.

Again at 0830 hours, we will begin another race around the same 4.1667 mile trail. The same will be done at 0930, 1030, 1130, and so on, every hour.

Runners must be standing in the starting corral when the next race starts or else they may not continue. Runners will also not continue if they choose not to themselves. No late starts once the bell is rung. Races will continue until only one runner remains, and at that point, once that person completes a loop on their own, that runner is the winner. All other runners are a DNF.

At 1930 hours, the races will be moved to a road out and back course and continue in likewise fashion every hour thereafter. At 0730 hours the next morning, races will continue on the trail loop.

Ohio's Backyard Ultra is considered a "Golden Ticket" Affiliate Race of Lazarus Lake's original Big Dog's Backyard Ultra. There are 10 international Backyard Ultras and 7 North American Backyard Ultras a part of this list of affiliations. The top 2 runners (in distance) from the 7 North American affiliate races will receive a "Golden Ticket."
