Great run, 'roos!
flr - you're sure to have been suffering a bit because of the heat - planned walking breaks definitely worth a try.
Do the folks feeling a bit fragile after last night's social deserve any sympathy? - I suppose so, they always commiserate when I have a hangover!
Did a re-introductory 3-mile plod before breakfast, now my sore throat is better. It was very slow, but OK - I hardly ever get even slightly ill, so I don't know how to cope at all if I get the tiniest sniffle - can't judge sensibly between carrying on regardless and resting.
