The Pan-Mass Challenge (PMC) is an annual bike-a-thon established in 1980 to support cancer research and treatment at Dana-Farber Cancer Institute. Riders come together to raise funds, with 100% of every dollar going directly to Dana-Farber.
With events like Winter Cycle, Kids Rides, and Unpaved, the PMC aims to raise $75 million by 2024. The organization also offers volunteer opportunities and a store for supporters to contribute to the cause.
