I know what broke my run, but I don't know how it broke it so badly. I ran on my lunch break, and was in the last minute of the first of the 5 minute runs, when my phone rang and cut off my podcast. Knowing it was my wife, I slowed to a walk and answered. I had a very short conversation with her - about 40 seconds - and when she hung up, the podcast restarted and I started running again.
But it was gone! I could barely run after that. I did push through and finish the runs, but I was so slow, so tired, and ached all over. It was going so well until the phone rang. I'm really starting to doubt myself.
