WESTWOOD (CBS) — Many participants of the Westwood mini Pan-Mass Challenge had a personal reason for riding — they, or a loved one, have battled against cancer.

“Today is all about people riding for people to earn money for people with cancer,” explained Allisa Freiberger, a young cancer survivor.

“It’s always tough a little back, it brings you back a little bit, I feel this is a way to give back with everything that happened with her,” she said.

Cancer-free, Alexa biked the ten-mile route and hopes to work her way to the PMC 200 mile ride.

‘Alexa’s Obstacle Course’ is also a stable at the event.

The Westwood event raised around $50,000. PMC Kids Rides can be found all over the state.
