Big Dog’s Backyard Ultra to be held in October via 19 satellite races around the world, including Hong Kong
- The race with no end requires runners to start on the hour every hour until there is just one person still going and will be held around the world due to Covid-19

Big Dog’s Backyard Ultra is due to take place in 19 countries simultaneously. The race that is usually held in Tennessee has made adjustments due to travel restrictions.
The race format is unique and its infamy lies in its mind-numbing difficulty. Participants complete a 6.7km loop. They have to start a loop on the hour every hour or they are disqualified. The race keeps going until there is just one runner left. The longest anyone has gone to date is 68 hours.
In a normal year, there are qualifying races around the world. A few other runners are also invited by Lazarus Lake, the race organiser famed for hosting the Barkley Marathon.
“Sometimes you have to be like the little wind-up car, that goes hell for leather until it hits a wall,” Lake wrote on Facebook. “Then it backs up and takes off in a new direction. This year is one of those times.
“With the Big's as the backyard world championship, about 75 per cent of our field was going to come from out of country. But there is some kind of a bug going around. Possibly you have heard about it. So none of those people were going to be able to come.”
