Yeah nutrition wise I did the same as last year, and as my long training runs. Cinnamon raisin english muffin with PB and honey with a side of water for breakfast. Normally eat a banana as well, but forgot race morning (which could have been part of the cramping issue I don't know). This has worked for me on 16-18 mile runs without gus, just powerade, while training. During this marathon I did a gu at about mile 9, then second was about 20. I was going to do one at the top of the hill that is from ~16-18 but then cramps started in legs and I was just focusing on those.
Start of race was high 40's (48/49), and when I finished just before 11 it was mid 60's. I had warmup clothes on until about 10 minutes before start, when I dropped to tech shirt and shorts. I have compression pants but only wear them in cold weather. I do however have compression shorts that I wear under my shorts, but they only go about half way down the thigh.
