Hi mate,
Try Hardcore History by Dan Carlin it’s a series of Podcasts they are amazing Blueprint for Armageddon is a good start it’s about WW1 and is fascinating I think there is five parts each about three hours long! But it’s just great. I’ll echo the iplayer comments Radio four comedy is great.
Fiction wise I’m addicted to Audible 😉 the app is really good as it allows you to book mark your position so when you fall asleep it’s easy to find your spot in the book. It’s also got a sleep timer to it will switch off if you want. So thats maybe worth a look.
Huge range of books too, good series to try are Arisen ( Zombie apocalypse job not too much thinking required!) Victor the assassin series by Tom wood is again worth a listen. There’s some great bio’s etc on there too The Nazi hunters is facinating all about SAS action in WW2 France and the hunt for the SS after the war.
Either way rest up, I look forward to hearing you’re back on the bike!
