Wayland Town Crier 8/19/10: Locals help Pan-Mass. Challenge raise record amounts. About 5,000 cyclists from around the U.S. and various countries participated in the two-day Pan-Massachusetts Challenge (PMC) earlier this month. Riders from both Weston and Wayland participated this year, some veteran riders and some new to the challenge. The ride has become a community and family event, where families ride together to support a loved one who is battling or lost the fight with cancer, and also just to help the cause. The 32nd annual PMC is scheduled for Aug. 6 and 7, 2011. Registration will open in January through the PMC website.
