A 100% human-powered odyssey from Squamish, BC, to the summit of South America’s tallest peak—Mt. Aconcagua (6,962m) in Argentina.
15 Countries. 20 Months. Over 20,000 km. 100% Human-Powered. (Bicycle. Foot. Kayak.)
Mark Sky’s journey begins in May 2023, as he pedals out of his hometown on a bicycle, setting his sights on summiting the highest peak in every country he crosses. But this is no ordinary adventure.
In Panama, Mark teams up with legendary expedition paddler Frank Wolf to face one of the world’s most treacherous challenges: kayaking the infamous 500km stretch around the lawless Darién Gap into Colombia. The journey takes a harrowing turn as they are taken captive, testing their resilience and resolve.
From there, Mark continues biking solo through Colombia, Ecuador, Peru, and beyond, determined to climb the highest peak in every nation.
His ultimate test? A daring solo ascent of Mt. Aconcagua’s most unforgiving route—the Polish Glacier Direct.
Mark’s story isn’t just about breathtaking landscapes or physical endurance. It’s a raw, unfiltered look at life on the edge—stories of triumph and heartbreak, corruption and bribery, perseverance in the face of robbery, immersion in new cultures and the deep longing for solid community. This is an adventure that strips life down to its essence, revealing honest vulnerability and untold lessons from almost two years on the road.
