Mick - thank you - I think the 16-week schedule I followed for the half-marathon (and which I followed fairly consistently not to say religiously) probably contributed to my slightly faster paces recently. I'm glad you don't seem to be getting the awful weather they've been having in parts of the States, - but I think you're over the other side, aren't you? Heavy rain is bad enough, but 6 feet of snow is impossible.
Ceal - the "pending 5k" will be on 6th December, so barely time to resume threshold runs if I take 10 days recovery. May just treat it as a fun run, - Eldest Son has suggested I do Greenwich, his nearest parkrun, and he'll do it too, plus a family friend whose little boy he often helps to look after, possibly even plus Middle Son who is about to move into a flat in the same area. (Come to think of it, if Middle Son is doing it, I shan't be allowed to treat it as a fun run!) - However, I'll be in London again over Christmas, and may be able to do something a bit faster on 27th.
Do you know a book called "Older, faster, stronger" by Margaret Webb? (Hope I haven't asked you this before, - I know I've mentioned it on the "Fetch" website, but can't remember about here). About older women running. The style is a bit OTT, but there's a lot of interesting research reported.
Chris Hob - I don't really race a lot; I try to do at least 3 races a year, at different distances, - gives me a target to aim for. But I'm not like Impey with his 74 parkruns! You run 4 times a week, then?
