If you rely on a pace chart in marathons like I do, and you're running New York, you NEED the NY City Marathon pace band calculator at the Nike website. It accounts for the terrain, including the big uphill of the Verranzano Narrows Bridge at the start, the hills at mile 8, 16.5, and the rollers in Central Park. You'll need to make an account, but then try this link. (The site is a little weird to navigate).
Another must-read site for newcomers (like me) to the New York City Marathon: Ron Horton's "Things I Wish I Knew The First Time I Ran NYCM". Thanks, Ron!
