About
Join the 46th annual Pan-Mass Challenge (PMC), an extraordinary event uniting thousands of riders, volunteers, and supporters in the fight against cancer. Taking place on August 2-3, 2025, the PMC is more than just a bike-a-thon—it’s a movement with a mission to fund cancer research and treatment at Dana-Farber Cancer Institute.
With nearly 6,800 riders and 3,500 volunteers coming together, the PMC is fueled by the strength of community and the commitment to making a difference. Every pedal stroke and every volunteer hour pushes us closer to a world without cancer. 100% of every rider-raised dollar goes directly to Dana-Farber, making an incredible impact on countless lives and helping to pave the way for groundbreaking medical discoveries.
Whether you’re riding, volunteering, cheering from the sidelines in Sturbridge, or supporting a loved one from afar, the PMC is an event that brings hope, health, and humanity to the forefront. Be part of this inspiring weekend as we work together to bring us “Closer by the Mile” to a cure.
