I have never broken 4hrs before despite 16 attempts. I seem to get to 22 miles and fall apart but I have never been this fit. Took 12 mins of my PB this morning so fingers crossed. 3.59.59 will do me. How about you what are you looking for?
Its only my second marathon but I was hoping to try for four hours but don't think I'm up to it. I will probably aim for 4.15 which will be 40 mins quicker than my first attempt (although I did run with an injured knee and really struggled).
