(MD) (Montgomery Parks) Join the Roots to Rocks team for a mountain bike ride exclusively for folks 55+. Our instructors will go over the basics of bikes and bike handling skills in a supportive environment. These rides are great for people who have some riding experience, but you don’t need to be a seasoned veteran. This is a perfect way to learn the basics of biking from certified bike coaches. We have a limited number of bikes and helmets available to borrow.
