Sean Nakamura is an insanely talented ultrarunner who just became the 4th person to complete The Great Eight - the eight original 100 mile races - in one summer. This includes the Old Dominion 100, Mohican Trail 100, Western States 100, Vermont 100, Angeles Crest 100, Leadville 100, Wasatch 100 and Arkansas Traveller 100. He through a couple other races in there for good measure (UTMB 100 and Tahoe 200!). Not only that, but he just hit day 3,223 of his on-going run streak. This is going to be an amazing episode!
