Luke, 14, of Manhattan said he has been cancer-free for three years and he’s riding to help raise money for other children battling cancer.

“I feel like though I’m done with cancer it’s still a part of my life and it’s my obligation to raise money for other kids who are still fighting cancer,” he told 1010 WINS. “Cycle for Survival helps me fulfill that goal.”

Since 2007, Cycle for Survival has raised more than $75 million through indoor team cycling events all to support rare cancer research led by Memorial Sloan Kettering Cancer Center.
