The last few runs haven't been very good. Had to walk during 2 parkruns (even though I got a PB on one of them), and couldn't complete another on the treadmill. I was getting a bit desperate thinking I was losing any fitness I've built up. And my left hip is playing up - something I haven't had since I started running.
I think that I've been trying too hard, then running out of steam. I decided today to do a long SLOW run. I set the treadmill to a smidgeon above my c25k graduation pace and set off, watching pointless on TV. 30 mind-numbing minutes later I completed 3 miles and 5k a minute later. And though I was sweating cobs, I wasn't shattered at the end and I even sprinted a little during the last minute.
So I've been over-doing it. I'm going to do more long slow runs and hopefully start enjoying it again.
Oh, and the radioactive orange Kayanos were awesome
