Thanks for the words TheEd!
Yup. Absolutely brutal in the second half. Drank everything I could but wasn't enough. Stopped for the loo at about 25k and the colour was not a healthy one!! After that I was just hanging on.
Glad to finish alive and plenty of sub 2:40 guys around/behind me so I wasn't alone in suffering!
Good news is my legs feel absolutely fine now, unlike previous marathons where I have been unable to walk or descend stairs... I actually feel fresh now I'm hydrated.
I have to admit am keen to find another. I have Abingdon again in Oct and was thinking of going for 5k/10k PB's in the mean time.
You reckon sooner is doable for another mara?
