Jepp, I was wearing a white Valley Striders vest. Got 3.55.02 which was a PB by 17 seconds!!
I am doing Wharfedale and Mont Blanc Marathon again this year so I better keep up my training.
Ah that was you ahead (I got 3.55.09) - I usually have a good finishing sprint but was in the middle of a near-death experience at that stage. Can still barely walk today, calves massively sore and swollen, overcooked my 1st 3P a little, I feel.
