I decided to run today after a two week break and was devastated to discover that I could only manage to run for about two minutes before getting out of breath - what has happened? I graduated a couple of weeks back and although haven't been for a run ( due to illness and then Xmas) didn't think It would make that much difference. I hadn't run outside before as completed the 9 week programme on a treadmill so expected a little bit of resistance. Wonder whether I'm going to have to start the programme again. Any suggestions anybody, I feel like a complete failure.
