I ran Boston in 2013 and had a terrible race, full of cramping, which is why I am extra paranoid about fueling this time. I have run flat marathons and done okay, but still have not mastered the final 10K without bonking a little bit.
Not sure a "big" PR is on the docket for this course, but I think as long as I don't cramp up/walk like I did in '13, I am definitely in PR shape. I think a conservative goal is sub-3:20, but I would be happy just to feel like I ran the course well.
My guess is that your '13 cramping had more to do with hydration and not running the course smartly. I had cramps last year from running to hard from 13-20 and not taking it easy once you crest heartbreak hill at boston college.
Start slow, and be steady the first 13. Don't make any big moves on the few downhills after the half way mark. Run steady but strong through the hills. Take it easy once you crest them and then make a big push from cleveland cricle to the finish.
