I nearly didn't bother doing this yesterday, i had bought a new phone that needed usb c adapter for the headphone, couldnt find it, stressed as aionly just bought it, it was getting late as i had decided to run when the temp was lower.
Everntually I decided to us my old phone, set my music up, listening to Hocus Pocus by Focus, to get me in the mood, it was playing fine, started the app, seemed to be fine, then the music stopped, so i checked and the app had stopped as well, started the app and began playing the music again, would't play, the memory card was removed, which had all my music onbut for some reason it had let me start playing for a while, no online music as i had no internet without me SIM.
Decided the app was working so i could run, butit had stopped again.
Gave the app one more shot and was fine, 2x8 minute runs wehn 1 minute running used to be very hard work. Amazing i did it. Still have that time dilation thing going onwhere i relive most of the first few minutes of running over and over hundreds of times before breaking the loop and time running as normal for the last 60 seconds.
