Mr V, Phil - Thanks, fellas. Yes, I'm sure you're right. My thinking really (though this will probably prove your point!) is that with the progress I'm making it's very difficult to know exactly what pace I should be targeting over the various distances. Whilst I'm delighted with the overall result of Sunday's 10k, the disparity between the first/last mile paces and those in the middle (7:03/7:11 v 7:30 average in the middle), probably shows that whilst I thought I was being quite aggressive with my target pace, in truth, I could probably have been even more ambitious. Just looking to avoid a similar undershoot this Saturday really. I'm happy to be patient with my body to make the adaptations to faster pace over time, but am less keen to show patience with myself in not fulfilling current potential! I guess over 5k you can just run hard anyway really, so 7:00 mile pace seems like a good initial pace to go out at - quick enough to target sub-22 but not so fast that I might blow up completely. What's sharpening my appetite for this weekend is I've got a little side challenge with another parkrunner I know through another (non-running) forum to get to sub-22 first. He ran a 22:01 I think it was last week, so the challenge decider now looks like being who can get furthest under 22:00 this week rather than who will get there first.
And Phil, thanks also for the advice regarding the races - I'll bear that in mind, though reading back the post you refer to, it probably misleads on the volume of races I am actually looking at - it's just there's a good variety amongst them rather than being multiples of each: -

There's a few either/ors in there, and it's only those marked with an asterisk that I'm likely to end up running. The exception might be the HPRC Grand Prix series which is run by the club I'm thinking of joining, though only the two marked with an asterisk will be raced, the other two probably just run as glorified training sessions to complete the series. Even the parkruns will become less aggressive tempo runs most of the time once the cricket season gets underway I'd hope. Does that seem more reasonable?
Regarding the songs, I do get stuck song syndrome / ear worms, but not in this particular instance. Though if we're making suggestions I'll kick off with The Liquidator by Harry J Allstars for Duck, and Stars on 45 for Curly.
