Sam Stow has pretty much done it all in a long career winning a number of races along the way, and finding himself at the front in some of Australia and the World's big races.

He's also the founder of Pop! Running and is on a mission to help runners and multi-sport athletes discover the joys of efficient and injury-free running.

As one of Australia's most respected distance athletes, he is also not immune to taking on a challenge, whether that's running and winning the Beerwah Marathon in sandals, or completing the 4x4x48 challenge while carrying a log.

This October he's raising funds for the Top Blokes Foundation with an incredible backyard ultra challenging forming a key part of the fundraising.
