The PMC Winter Cycle is a charitable spin event benefiting the Dana-Farber Cancer Institute (Dana-Farber), held each year at Fenway Park in Boston, Massachusetts. The PMC Winter Cycle, a spoke in the wheel of the Pan-Mass Challenge (PMC), kicks off the organization’s yearly fundraising campaign with six 45-minute, high-energy indoor cycling rides led by popular local spin instructors. The day-long event brings together hundreds of people of varying athletic ability who channel physical, mental and emotional energy to fight cancer by raising money for Dana-Farber. The 11th PMC Winter Cycle will take place on Saturday, January 31, 2026, at The 521 Overlook, located in center field, offering participants an iconic view of historic Fenway Park as they ride. As with all PMC events, 100 percent of PMC Winter Cycle rider-raised dollars directly benefit lifesaving cancer research and treatment at Dana-Farber. In 2025, the PMC raised a record-breaking $78 million, bringing its lifetime fundraising for Dana-Farber to $1.125 billion since 1980. The PMC is Dana-Farber’s largest single contributor, accounting for 67 percent of its Jimmy Fund’s annual revenue. For those interested in spinning during the PMC Winter Cycle, there is a non-refundable $50 registration fee and a $500 fundraising minimum per session. To become a top fundraiser, or Pacesetter, participants must raise at least $1,500. All fundraising minimums must be met by April 1, 2026.
