Gosh, I never heard about the collapses...not good :o(
Himpy, I was in a white top, not orange - I'm sure you passed me though! my fella was all in black and mostly a few feet ahead trying to make me go faster, didn't quite work!
Think I'll be using flatter 10ks with an earlier (hence cooler) start for trying to beat my 52.30 pb.... I'm going for the bluewater 10k in august, hope it's flat! (not quite sure I'll be ready to pull out a PB in less than a month!)
Anyone going for the bluewater one?
