This Former Royal Marine is One Badass Ultrarunner

The latest episode of Salomon TV explores the life of British ultrarunner Donnie Campbell, reigning British Ultra Trail champion. Campbell grew up in Scotland, joined the British Marines at 17, served in Iraq at 18, and now spends his time putting up insane times on trails in the Scottish Highlands. Here, he talks about what it takes to just keep running during 14-hour pushes, why he prefers to just bring map and a compass into the mountains, and how he developed into the athlete he is today.
