A quest by bike, boat, and foot

In 2023, climbers Tommy Caldwell and Alex Honnold set off from Colorado on

a mission to make it to Alaska’s Devils Thumb with minimal help from motors.

Poor winds up north required the use of a boat engine, but otherwise they

pulled it off: a 55-day expedition, powered by human strength, to reach and

summit one of North America’s most challenging peaks.
