... that awful sound this morning was me singing along to my iPod after successfully running for more than 20 minutes today!
After coming to a grinding halt at the half way stage of W5R3 on Friday, I made up my own playlist and ran to that today. I found it SO much more fun and the 20 minutes passed quite quickly. My legs started to ache around the 15 minutes or so mark, but I soon forgot about that once Paolo Nutini started singing!
Really chuffed to have got myself past the W5R3 milestone - it was always going to be a tough one for me physically and, especially, mentally. I can really recommend setting up your own playlist to anyone else who is struggling.
Thanks to everyone for their support and advice since Friday!
