SAFD… and running is for listening to music. It’s the only sustained time I have to indulge my love of music, so I make the most of it! I have a bunch of different playlists, including a general running one with a couple thousand songs in it to shuffle up. Others are thematic: Totally 80s (which is mostly alternative 80s stuff like Love & Rockets, Adam Ant, New Order), Dead Run (all Grateful Dead), Just the Classics (all classical, mostly symphonies), Big Band Baybee (swinging big band tunes from the 40s), All That Jazz (classic jazz - everything from Sidney Bechet to John Coltrane to Miles Davis), Speed Kills Del (all fast stuff to motivate me for speed work), Runnin’ & Rhymin’ (rap and hip hop), Dark Side (all Star Wars), Flooooow (all EDM), The Nick Rhodes of It All (all Duran Duran), Go For Baroque (all chamber music with a lot of Vivaldi and Handel). Oh and special Halloween and Christmas seasonal playlists, too. I also love taking a long run to listen to an entire amazing album in recorded order, as the gods and musicians intended - if I had to pick a favorite, it would probably be The Police Synchronicity, but the TRON Legacy soundtrack by Daft Punk is a close second.
I do sometimes do a podcast if I’m falling behind on those: I prefer to podcast in the car, though.
