Kiddos, ages 3-13, can ride in the Mercer Island Summer Celebration Obliteride Kids Ride on Saturday, July 9. They will start their ride at Mercerdale Park, pedal a safe 1-mile down to Sunset and loop back. Ride this loop once, twice or three times; it's all good fun to support Fred Hutch. Kids and their families can stick around after the ride to enjoy the festivities at Mercer Island Summer Celebration.
