The heat poured on in Virginia - record temperatures much earlier than they typically experience. I had pretty severe thunderstorms all throughout the South. I mean, weather is a huge component of doing something like this. So over the previous 46 days, throughout the entire month of June and then some, you must have had quite a bit of rain at various times on the trail, no? SIEGEL: Now, you just wrapped up this - on Sunday. And then as I approached the end of the route, I was putting in, you know, some nights only an hour on, you know, at times when I met my crew and then a half hour out on the trail and just sleeping on a sleeping pad with a bug net over me. Those nights I was getting, you know, maybe four to five hours of sleep. As I went on, the trail and the terrain became more difficult as long as I, you know, as well as I was trying to put in 59 and 58-mile days.

Like, for me that felt like a, you know, and 8, 9-hour night if I was, you know, in normal life. There were times when I got, you know, five, six hours of sleep, and, you know, six hours was excellent. And really, it's a mix of sports foods along with real food.

I'm eating every 20 to 30 minutes, trying to consume around 100 calories each of those times. JUREK: Well, eating is something that you become accustomed to doing while on the move. SIEGEL: How did you eat and sleep during all that time? I mean, the trail becomes so steep and so technical at times that walking and hiking is really the most efficient way to travel. And I was doing a combination of running and hiking. JUREK: Well, a lot of the time, I was moving between three and four miles an hour. How fast were you moving during those 46 days?

Actually, the average hiker drops out and doesn't complete the trail. SIEGEL: It takes the average hiker between five and seven months to complete the entire trail. Scott Jurek, welcome to the program and congratulations. That's how long it took the ultra-marathoner to hike the 2,189 miles of the Appalachian Trail, which passes through 14 states. Scott Jurek's record time was 46 days, eight hours and seven minutes. We are about to hear from a record-breaker.
