I went for a pretty substantial run with my friend David on Saturday. We starded at Clerkenwell, got to the north side of Blackfriars Bridge, ran along the Embankment to Westminster Bridge then back along the Southbank to Blackfriars Bridge. It was lovely and a route I'd recommend to anyone.

I enjoyed the post-run buzz afterwards (probably a mixture of smugness and endorphines) but to be honest, I'm still feeling pretty exhausted from it two days later. And I ACHE!

What's going on?

I'll tell you what going on - I didn't warm up properly, didn't stretch properly and didn't get enough rest afterwards. All text-book mistakes and as a former Personal Trainer, I should know better. I'm not sure why I'd think I am exempt from these very basic rules of exercise but yes - warming up is cool.
