Following in the footsteps of writers like Cheryl Strayed and Bill Bryson, 4000s by 40 gives voice to the universally relatable journey of dealing with middle age, and doing so while stumbling around in New Hampshire's 4000-foot mountains.

Faced with the fact he couldn't stay in his 30s forever, Matt Larson fled to the mountains where no one could remind him how old he was getting. From failed summits to hitchhiking with strangers, 4000s by 40 is one man's quest to conquer all of New Hampshire's tallest mountains before turning 40, while trying not to get himself killed in the process. An adventure of mistakes and self-discovery, Matt's journey led him from idiocy to expertise, and ultimately newfound humility, when a series of health crises derailed his life. Getting over the hill took him over quite a few hills, and taught him that no matter how many mountains we climb, greater challenges await, each one leading us closer to discovering our best selves.
