Join Belmont’s Burnin’ by Ray for an outdoor workout to celebrate the life of Cleo Athena Theodoropulos this Saturday.

The “Best of Boston”-winning gym is hosting a two-hour charity outdoor boot camp at the Winn Brook Elementary School field in Belmont on Saturday, Aug. 17 at 10 a.m. to honor Cleo’s energy, kindness, fierce athletic drive and abundant spirit. 

Tickets are $25 and can be obtained here. All proceeds and donations would benefit the Dana Farber Cancer Institute.

Cleo, who was an outstanding figure skater and varsity field hockey player, was a junior at Belmont High School who died on April 22, less than one week after her diagnosis with Ewing sarcoma, due to a cancer-induced fatal stroke.
