I went along to the first park run event near me today, a 5K time trial. It happens every Saturday and it's free, very friendly and nicely organised. Anyway, despite Friday night's drinks and quite a late meal, I finished in 24.36 which I was happy with despite a killer stitch that slowed me near the middle. Looking at my historic times on the Garmin I think this was the fastest I've done 5K. I'm really glad I went and met some fellow runners and I'm certain I can beat my time in future.
