I listen to a lot of podcasts. There are podcasts on any subject you can imagine.
Just started listening to a series by Warden's Watch about the tragedy of Kate Matrosova (an accomplished mountaineer who died attempting a Presidential Traverse in the White Mountains of NH). No idea if the rest of their shows would appeal to me - but this series of 4 does.
Started listening to "In the Red Clay." True story.
I also started listening to Fastest Known Time. This podcast focuses on trail running. I don't participate but like to follow it. They have done a few lately about electrolyte replacement which is applicable to anyone, especially anyone who likes sports - endurance or speed.
