Here is a Google Earth view of one lap on the Ironman NY US Championship bike course. Can't ride it ahead of time, so I guess aside from driving it, this is the next best thing.
I hope the trees don't block too much of the view, but I should be grinding out some serious watts over this course anyways.
Couldn't have an exact trace since its on a highway, but close enough. One loop is about 2,000 feet of elevation gain. Should be a great chance to hammer it too since there are no real big climbs, just long ups and down.
