Well, I am pleased with my Eastleigh result, a "chip time" of 49:57 for the 10k.
That's my best result since 2001. In 2001, I was running with the Alresford running club twice a week, which was always a hard run as I was the slowest person there; plus two more easy runs a week on my own. A total of four runs a week, two hard, two easy.
In the spring of 2001, I ran three sub-50 10ks (all slightly faster than yesterday's).
I haven't been as fast as that since. Part of the lesson may be that with the much larger Winchester running club, it's too easy for me to run comfortably with the slow group and not push myself.
