I think the rouch mcmillan equivalent of a 451 is like a 245 for the marathon! I know the new york course is hard though. You and 11 are both gonna kill it.
(I know 11 is running another marathon similar weekend)
9pm yesterday with 4 x 1 mile in a crappy 520ish pace. Should have been faster but I am sick and the toll from the mileage has gotten my legs feeling a bit tired. It was also my bday - so I was a bit distracted!
