Four Australians have completed a mammoth feat by running more than 3,300 kilometres from the southern tip of Florida to the Canadian border in 79 days.
The plan originally involved the foursome running 80 marathons in 80 days, but the crew decided to finish a day early with a double marathon.
The time frame for running across a continent might seem tight, but as Lightning Ridge's Rory Cheal explained to ABC News Breakfast during the journey they could not get any more time in America.
