Thousands of runners are taking on the 26.2-mile TCS New York City Marathon today, with crowds lining the streets to cheer them on every step of the way.

For many runners, this moment represents months, even a full year, of training, dedication and sacrifice. Along the course, family members, friends and strangers are showing their support, offering encouragement as runners push toward the finish line.

This year, the marathon is bringing a new experience to the Mott Haven section of the Bronx. For the first time in 15 years, the course has changed, taking runners farther along Alexander Avenue and introducing them to new faces and neighborhoods ready to cheer them on.

With the final wave of runners heading out at 11:30 a.m., the excitement continues across the five boroughs. New Yorkers are coming together to support runners as they take on a challenge many have spent the entire year preparing for.
