George...(& all other NYC marathon runners)
You can get a shuttle from JFK to Manhattan, which is far cheaper then the yellow cab. MInd you, its a flat fare into Manhattan from JFK. So if you can share a cab with another run, so much the better.
Remember - Flat fare is only valid coming into Manhattan. Going to JFK, you pay the full whack.
If you get a chance, go to Woodbury Common shopping outlet. Catch a bus from the Port Authority Bus station. Its a all day thing, so best done after the run on Monday. OK, i know the legs have seized up, you can hardly walk and the thought of wondering around shopping....well at Woodbury Common the money you save and the stuff you can buy. It's worth it. I have a fortune shopping there. Fancy a bite, check out Rosie O'Gradys.
I done NYC for 5 consecutive years. It's great. I'll miss this year due to injury sustained running FLM in April and lack of race fitness.
GOOD LUCK TO ALL NYC runners.
