ta...it has been a right old downer....but i suppose when you're keen and run well some might feel it's being rubbed in their faces!
They shouldn't worry, as i look at plenty of runners faster than me and think cripes they're fast...it's all relative.
I reckon you could comfortably take 2mins off your 10k without that hill...i lost 5 1/2mins from Wokingham half to Wycombe once....if your mind isn't 100% up for it it's easy to lose time quickly.
There's some fast 10ks in oxfordshire later this year I believe...otherwise maybe Slough 10k (next to Black Park rather than dodgy Slough). Maybe give them a try.
Maybe even Wooburn 10k... 1 km hill, but you get the same hill at 9k to smash down.
