New York

This feature-laden Gmap lets you build walking tours/workouts by auto-plotting the distance and elevation between multiple points, plus provides markers for along-the-way amenities like water fountains, restaurants, and bathrooms. Input your physical deets (height, weight, etc) plus time taken on the route, and it'll calc up your calories burned -- or would've burned, if you weren't so busy stopping at water fountains, restaurants, and bathrooms.
