The 19th annual W-Day 5K Cat Challenge at Westchester Country Day School includes a 5K run/walk and 1-Mile Fun Run to encourage kids and adults of all ages to get moving, set goals and have fun! There is even a Little Cap Lap (ages 3-4) and 50-Yard Diaper Dash (2 and under) for young children. Participation is open to the public. Also known as "The Hobey," the event is held in memory of Hobey Ragan, devoted father and dedicated Westchester Wildcat fan. Proceeds benefit WCDS Athletics, and a donation is made to the American Lung Association.
