In a 100-miler, anything can happen. Speed isn't your biggest thing, you need to learn how to mentally get through it. It is very mental.

Virginius Pass, go across the Talus slope and pick up the route through the notch, it is steep, slippery, brutal.

Training-wise, I don't get too specific. I don't put a schedule together and tell myself I have to stick to this. I run on feel, so every day I go running, I don't know how far I'm going to go. If I feel great, I'll go further and if I don't, I'll back off the throttle.

I look at road marathons as a totally different sport. Those guys are stupid fast. It is unbelievable. I might be a top ultrarunner, but put me in the field with those guys and I'm just another guy trying to break three hours. Road-running is far more competitive. In ultrarunning, after these long races, we all chat with each other at the end and have a beer. The camaraderie is awesome. But don't get me wrong, winning is fun.

Be careful crossing above the waterfall, it's a fatal spot.

Watch out for cliffs on the left. Fatal spot again.
