This week on The Drop, Thomas, Robbe, and Meaghan talk about the new Saucony Endorphin line, including the Endorphin Shift 2, Speed 2, and Pro 2 (20:37). Then, Thomas and Meaghan are joined by Stefanie Flippin. She's a foot and ankle surgeon by day and an ultra runner who recently won the USATF 100-Mile Championships. They talk about her start in trail running and evolution to ultras, her training habits, the similarities between the marathon and the 100-mile, and much more (31:40).
