Cork Waterbury: We're gaining momentum so Dirty Thursdays is officially a weekly event! Join Cork Waterbury & Waterbury Sports every Thursday for a fun evening of group mountain biking at Perry Hill & post-ride drinks at Cork. Bring your bike to Waterbury Sports for any minor adjustments before 6pm. Group rides leave from the parking lot between Waterbury Sports and Cork Waterbury at 6:15pm and head over to Perry Hill. All levels & abilities welcome! Post-ride, head to Cork Watebury for $4 local draft beers, wine specials, and killer fare from the Cork kitchen crew.
