If running a marathon seems like an exhausting prospect, then spare a thought for the British couple that ran a marathon every single day for 15 months. The mammoth feat was part of an epic plan to run the entire length of South America– ,504 miles to be precise.

Katharine and David Lowrie became the first people to ever run the length of the continent when they crossed the finish line in Venezuela last week. But their arduous journey began way back last year on the first day of the London Olympics when they set off from the southern tip of Chile.

The intrepid pair was determined to complete the journey and strode on despite all sorts of unpleasant conditions, be it hurricane-force winds, knee-deep mud or slippery ice. The temperatures they faced were no better, ranging from one extreme (14 F) to another (113 F). And if running miles in these conditions wasn’t bad enough, the couple did it all while they dragged their supplies behind them. There wasn’t much reprieve at night either, with the couple hunkering down in wonky tents as they tried to gather their energy for the next grueling day of running.The Lowries say they went through 10 pairs of shoes during the trip, although they ran a significant portion of their journey barefoot, kind of brave when you consider the Amazonian insects that were swarming them and the snakes that assaulted them. Those critters did come in handy a few times, however, with the couple admitting to eating termites for breakfast when they ran out of food at one point.

The pair says they made the record-breaking run to raise awareness about the importance of the planet’s forests and ecosystems and to raise money for conservation.
