David Goggins 48 Hour Challenge – 4 Miles Every 4 Hours | Lex Fridman

I ran 48 miles. Got it done. For me, this was exceptionally difficult, mentally & physically. I recorded a clip after each session, saying something I’m grateful for. Thanks to David Goggins for the challenge, and to my stubborn brain for refusing to quit. The outline for the video is below, but first some relevant links:
