SAFD: Training and some races - I listen to a smart playlist that has the last 3 hours of songs I've favortied in Apple Music - this way it doesn't get too repetitive.
SAFD: If I'm doing an outside run then its just me. Treadmills I will usually watch a show, I have found cartoons tend to work better as I need something I don't have to pay to much attention too. For the marathon build going through the Star Wars series, watched the Phantom Menace, Attack of the Clones and The animated Clone Wars move during long runs during my half build earlier this year. Then moved on to the Clone Wars cartoon series. If I make it through all of that on to Revenge of the Sith and Bad Batch. (I hope the weather is good enough it doesn't come to that ).
Mythbusters has also worked well, tried Sitcoms like Seinfeld, and How I Met your Mother, but they didn't work at all. Neither did Band of Brothers, required way to much attention.
