Charlie Engle is an addict who runs and a runner who writes. He’s not just any kind of runner; he's the first to run across the entire Sahara, and now, he’s attempting to become the first athlete to trek from the lowest point to the highest point on every continent. It’s a fitting pursuit for an individual who has experienced extreme lows, like a 21-month stint in prison and being kidnapped at gunpoint in Kenya, and the extreme highs of bouncing back and forging ahead. Luckily for all of us, Charlie addresses everything with complete candor in this conversation with host Justin Gignac.
