Cancelling your race entry
Entrants who officially cancel their entry to the TCS New York City Marathon will have guaranteed entry to the following year's TCS New York City Marathon if they did not also cancel in the previous year.
All TCS New York City Marathon fees are non-refundable. If you cancel your entry, it cannot be reinstated for any reason for the current year's TCS New York City Marathon. If you cancel this year (and did not cancel last year) and you want to guarantee your entry for the following year, you'll need to apply for the following year's race during the application window and pay the processing and entry fees required.
Check out the TCS New York City Marathon website for more details on cancelling your race entry.
