In today's episode I talk to Scott Loughney about an incredible 640 km ultrarunning challenge in the highest mountain range of the world.  Scott together with Ryan Wagner and Upendra Sunuwar successfully linked Katmandu, the capital of Nepal, with Everest Base Camp, a round trip distance of 640km. We really get down into the weeds with this one about the nuances of training for and then completing such a challenge.
