Your NYC elevation graph is in meters, you bozo.
Really hope you're a John Mulaney fan!
At CIM you gain 600 feet while at Boston you gain 900. Both have similar elevation loss.
NYC is a tough marathon. The bridges are tough. CIM and Boston are similar. On paper Boston is tougher but let's not pretend CIM is a roller coaster downhill. You drop the same as Boston and do a fair amount of climbing. There's a reason USATF allows OTQs at CIM and not on something like St. George.
Look at a consistent elite like Craig Leon. He notched a small PR today but has run similar times at Chicago. He always seems to be in that 2:13-14 range and ran 2:13 today. Is CIM fast? Yes. But I'll go maybe a minute or two max on a pancake flat course (if that).
Two more points: US Marathon Champs was today (a lotta people to run fast with) and pretty perfect marathoning weather. It was a recipe for success today.
Also yeesh stop hating on people for running well. Pick people up. Be happy for people. You'll live your best life that way.
