The next time you’re feeling a little discouraged about going for a run, take a look at these guys.

This past weekend, four Canadian men in their 80s set a new world record for the men’s 4x800m race at the Ontario Masters Championships, according to Canadian Running Magazine.

Ed Whitlock, 82, Earl Fee, 84, Ray Wardle, 80 and Bill Thompson, 82, completed their relay in a record-breaking time of 14:24 which was previously set by a group of Australians at 16:01 in 2010.

A YouTube video shows Whitlock passing his baton off to Fee and noted it as one of “the greatest exchanges in track history.”

Fee ran a 3:04 to set the world record for the over 80 age group.

It seems like age is simply just a number, especially when it comes to running. For example, even though the world’s oldest runner Fauja Singh, 101, couldn’t provide his birth certificate for an official spot in the Guinness Book of World Records after running the Scotiabank Toronto Waterfront Marathon, he still became an Internet sensation in 2011 after reaching the finish line in eight hours back.

And earlier this April, Bill Iffrig also made headlines after the 78-year-old was one of the first men captured on video to be shaken by the Boston Marathon bombings. Iffrig was running his third Boston Marathon and ended up finishing the race, according to the Los Angeles Times.
