Phil you have the advantage of being comfortably sub 3 and then some. SOme of us on the thread are just on the cusp.
As for the Xempo stuff, I think it's subtle enough not to make you look like a twat when you are wearing it. Most of the non-running world have no idea about them or how fast you need to be to achieve each colour.
For those worried about running over distance, I've said it before and to save you all scrolling back TURN YOUR AUTO LAP OFF! Lap manually under every mile arch. It gives you something to focus on and you know for certain that you have run a mile and you have a precise split time.
I don't want to be reading on here on 14th April that you good folks have missed out by 30 seconds because Garmin measured the course long.
Strangely I felt the same Speedy. Tedious first 10 miles but then by the time I got to 19 I felt like I could run and run and run. Glad to bring the taper on now though. Confidence building new pb at the park run yesterday of 18:20. Only 1 second off my all time pb.
I was going to be all sanctimonious and comment on who on earth fancies a burger after doing a marathon until I realised that after Frankfurt, there were 3 forumites who ate at McDonalds before hitting the bar!
