Kate and Caroline Stevens will run the 26.2-mile New York City Marathon together on November 1, 2026. The sisters are participating through Fred's Team to raise funds for pediatric cancer research at Memorial Sloan Kettering Cancer Center.
Why it matters
The siblings are participating to honor the medical team that treated Kate, who was diagnosed with acute myeloid leukemia during childhood and required a bone marrow transplant. Their participation highlights the long-term commitment to supporting research for pediatric cancers.
Since 1995, the Fred's Team program at Memorial Sloan Kettering Cancer Center has raised over $136 million for cancer research. The sisters' participation supports this ongoing initiative, though the specific research projects to be funded by this year's race have not been named.

Health Landscape
This effort aligns with established fundraising models for Memorial Sloan Kettering Cancer Center's pediatric oncology research programs. It reflects a broader trend of survivors engaging in athletic advocacy to bridge the gap between clinical outcomes and long-term research funding.
Survivors of childhood leukemia often require lifelong monitoring for treatment-related side effects like endocrine dysfunction. It is worth discussing personal long-term health screening needs with your physician if you have a history of intensive pediatric cancer treatments.
The takeaway
This story underscores the importance of long-term follow-up care for childhood cancer survivors who may face lasting treatment effects. If you are a survivor, consider speaking with your doctor about specific screenings for potential late-onset effects related to your past treatment.
