I'm very happy to report that I've just had one of those runs where it all felt really good. It's a frosty morning, but it didn't rain much over the past 24 hours, so no nasty ice puddles, just a lovely crisp morning. I ran my old route along the canal, and it was glorious.
As I'm still working my way back from injury, I did just 20 minutes, and at a much more sane pace of about 7.3 minutes per km this time. I felt good, I felt like I could have run further, but I wanted to end feeling could, so as not to give myself an excuse for bottling it next time.
Slightly related note: my right knee and left calf hurt. Not from running though. I was carrying concrete blocks to the car at the local builders merchants, and somehow managed to trip and go flying concrete block in hand! Ripped my jeans, grazed my knee and left hand, badly dented my pride :/
On the plus side, none of that has damaged my ability to run, thankfully, and I didn't seem to have any issues from it. It's all good.
Thanks as always for your support and wisdom. Happy running!
