London is indeed a fast course - if you are at the front. It's the other 30,000 people that seem to slow it down!
Am planning on a 5 mile PB on Boxing Day. How is this possible? Never run a 5 mile race before!
I think that Barcelona is a faster course, so plan sub 3 in Barcelona and then soak up the atmosphere in London with a nice gentle 3.30.
Boston is great. I have run a few big city marathons and the support in Boston is amazing. Ran in 2001, and 2006 & 2007 ran London as well. I thought in 2014 they were too close to run both.
Forgot to say, that I was much more disciplined in my taper this time, i.e. resisted the temptation to add miles to the my schedule. To be honest, by the time I got to the taper, I fancied the rest!!
