On Aug. 7 and 8, two Wareham residents — Katie Moulding and Nichole Stahmer — will participate in the annual Pan-Mass Challenge, a two-day 211-mile bike-a-thon across Massachusetts that raises money for cancer care and research.

Along with more than 6,000 other cyclists, Moulding and Stahmer will follow one of 16 predetermined routes that range in length from 25 to 211 miles in the hopes of raising a combined total of $52 million for cancer research and patient care at Dana-Farber Cancer Institute, a press release from the Pan-Mass Challenge explained.

The challenge was reimagined last year due to covid-19, and organizers said they were excited to offer a traditional in-person ride this year — though reimagined solo routes are still an option. 

“We couldn’t be more excited to bring our passionate PMC riders, volunteers, donors and sponsors back together in person for PMC Ride Weekend this year,” said Billy Starr, the founder and executive director of the challenge. “Cancer doesn’t stop for anything, even a global pandemic, and funding for research, treatment and care is as critical as ever.”

Registration for the 2021 Pan-Mass Challenge is open through June 30. For more information, visit: www.pmc.org/ride.
