Managed W7R1 today... although I had a late night (4 pints of beer, half a bottle of wine) and an early morning (big breakfast, lots of coffee) and realised just as i got changed i hadn't drunk any water all day - so i had some gulps from a tap.
I didn't feel too bad but was aware I probably wasn't as prepared as I should be!
Anyway, managed the run but did 3.4k, well under my w6r3 of 3.75k. But given the circumstances I guess i should just be chuffed that I made it through!
