Barrington will be well-represented at the 40th annual Pan-Mass Challenge.

Twenty-seven Barrington residents signed on to participate in this year's event, which takes place Aug. 3 and 4. The group of locals will join more than 6,600 other riders cycling up to 192 miles to raise money for cancer research and treatment at Dana-Farber Cancer Institute. 

This year's PMC riders range in age from 13 to 88 and include everyone from seasoned triathletes to weekend warriors. Many ride to honor a family member or friend who has battled cancer, while more than 950 riders and volunteers are cancer survivors or current patients themselves.

Participants are required to raise between $600 and $8,500, depending on their chosen route, though the average cyclist raises more than $8,825.

This year's fund-raising goal for the Pan-Mass Challenge is $60 million. The Pan-Mass Challenge bike-a-thon raises more money for charity than any other single athletic fund-raising event in the world.
