I’ve been looking for a route map that shows the different courses for the three colour-coded corrals that the ING NYC Marathon uses. The data here in this file is collated from the ING NYC Marathon Guide and also from a third-party site that uses Google Maps as its interface. The latter had some deficiencies which this file seeks to correct. Also include mile & km markers. Would like to enhance this file with hydration stops and toilet facilities but no data on that yet.
