The NYC Marathon was my first marathon, and it was an unforgettable experience! There are aid stations every mile, and the race is exceptionally well-organized. The course is hilly (there are a lot of bridges), so adding hills to your training is a must. The crowd support is absolutely incredible, and it's pretty constant throughout the race (except on bridges). The expo is INSANE and huge, but it's possible to dash in, grab your bib and (very nice) shirt and leave. If you have the chance, don't miss out on this amazing race!
