New York City Marathon

Undue is thrilled to once again be hitting the streets of New York City for the 50th anniversary of the iconic five‑borough course.

We’re incredibly excited to again partner with the TCS New York City Marathon and to be fundraising for this pioneering initiative, making a real difference in the lives of our neighbors. To support our athletes’ journey to the start line, Team Undue runners receive complimentary access to Runna, including base training and the 2026 TCS New York City Marathon Training Plan.

Imagine the impact of clearing billions in medical debt – a burden that disproportionately affects uninsured, under-insured, and low-income families in the very city we love. This vital program relieved billions in medical debt for 500,000 working-class New Yorkers. By running the TCS New York City Marathon with us, you’ll be raising crucial funds to help sustain and expand this vital program, giving New Yorkers a fresh start and a chance to thrive. Every mile you conquer will bring us closer to a city where everyone has access to the healthcare they deserve, without the crushing weight of medical debt. Help us take a bite out of medical debt and support the campaign, one stride, one donation at a time!
