“Orogenesis” is the geologic process of mountain building — a gradual evolution powered by unfathomable forces that expand across and transform broad swaths of the landscape.

Orogenesis is also set to be the longest mountain biking trail in the United Sates. At 3,500 miles, this new route stretches through Washington, Oregon, California, and then it connects to the existing Baja Divide bikepacking route to add another 1,600 miles to San Jose del Cabo at the southern tip of the Baja Peninsula. The creation of such a trail is an absolutely monumental vision, and endurance cyclist Kurt Refsnider will be guinea pigging his way down the full length of it for the remainder of this year as the first person to attempt the ride in its entirety.

In this episode, we talk to Kurt Refsnider about the history of the trail, what drew him to it, and what to expect along the way. We'll then be checking in with him over the next few months as he makes his way from the US/Canadian border to Mexico.
