Dave and Chris are joined by Chris's pal (and former boss) Andrew Leland, who talks them through how he went from being sedentary to a marathon runner. Andrew discusses why he started running, the program he used to get in shape, and what his running journey was like, including the differences as a runner with retinitis pigmentosa. After, Dave and Chris talk about the scientifically ideal running playlist and go through Dave's and the listeners' playlists to see how they compare.
