More than 1,000 people headed to the Greenwich Equinox Sunday morning to participate in the fight against rare cancers.

The Cycle for Survival movement is aimed at raising funds and awareness for rare cancers. Organizers say 100 percent of every dollar raised goes toward groundbreaking research and clinical trials led by Memorial Sloan Kettering to change the way cancer is treated and diagnosed.

"Fifty percent of all cancers are rare cancers, so it's not as uncommon as you would think. So to have a way to fund for these rare cancers and to dedicate resources, will help millions of people," says participant Omar Mureebe.

Cycle for Survival has raised more than $200 million for research since it was founded in 2007.

Cycle for Survival's founding partner, Equinox, will lead rides in 16 cities across the country in January, February and March.
