For those of us who look at running 100 miles as a challenging goal, the idea of going 200 miles or more seems incredible.

My guest this week is David Theriot. He's placed among the top finishers in several 100 mile races, run the Grand Canyon rim-to-rim-to-rim, ran in Western States 100, and the Tahoe 200.

Now he has his sights set on the Triple Crown of 200s – running the Tahoe 200, the Bigfoot 200, and the Moab 240 all in the same year.

David also has a podcast for ultra runners: The Run Theriot Podcast. https://www.facebook.com/runtheriot
