This event celebrates the life of Cristian Acosta-Flores who passed away on September 1, 2014, one day shy of his 19th birthday. Cristian’s life was cut tragically short due to complications from an undiagnosed enlarged heart. His big heart always lent a hand, encouraged others, and cared deeply for those around him. Walk, run, stroller, skate, bike or surf anytime during the virtual event to support SCA prevention and snap a pic to submit.
