Nearly 120 Wellesley residents will be among the 6,000-plus cyclists taking part in this weekend’s Pan-Mass Challenge (PMC), which will raise tens of millions for cancer research and patient care at Dana-Farber Cancer Institute. Many participants have lived with cancer themselves, or ride to honor those who have died or are too sick to ride.

This year’s PMC returns Aug. 7 & 8 as a group event, though participants also have had the option of charting their own course in light of the COVID-19 pandemic.

The PMC includes include 16 routes – from 25 to 211 miles. Numerous routes, including a 100-mile one, start at Babson College in Wellesley.

There are various ways to give to PMC riders’ fundraisers, including searching riders by name. Here’s the list of Wellesley riders provided by PMC.
