Hi, I've been reading your posts with interest as I'm hoping to pb with a sub 3:30 marathon at London this year. My best is 3:36 in 2011 at the Boston Marathon, which I read you've also done (cool race isn't it?), but i've been parked on 3:45ish time since. I'm coming to training a stone over my optimum running weight and with annoying shin splints which I've hardly ever had in 8 years of running. I'll be reading your posts and hoping you stay on track. I'm impressed with your food diary above...I'm trying to cut down on junk, but can't eliminate it entirely. Good luck with your training. I hope we both get our sub 3:30 times!
