This 26-mile tour of the five boroughs isn’t just a race to test your physical limits. The iconic TCS New York City Marathon inspires others to give back to their communities, partnering with nonprofits like GallopNYC to raise $520M in donations since 2006. Runners from 148 countries totaling more than 50,000 will descend on New York City for what is known as the city’s most important day in sport.
