Who you're running with

Ben Christensen

Forester · CEO · Ultrarunner

My life's work is trying to save U.S. forests.

I'm Ben Christensen. I founded and run Cambium, the first tech-native regenerative forestry company. I've spent ten years learning and working on what makes American forests better for everyone. Outside of that I've also run Marathon des Sables and the Denali 135, which is how I know I'm gonna learn something new running 250 miles.
