The positive effects of cycling are trying to take down Parkinson's Disease. Three Denver area women created the project, 3 4 Fighting Parkinson’s, after they were inspired by friends plagued by the neurological disorder. Having learned of the possible benefits of bicycle therapy for those with the disease, these women saw their passion for riding as the perfect way to help find a cure. Join them and others for a 55-mile ride around Denver or a five-mile family ride to raise money for the Michael J. Fox Foundation for Parkinson’s Research. Sat 8:00 a.m.
