Elementary and middle school students can have fun and stay fit this summer by taking the Cherry Creek Fitness Challenge. Just enroll online and keep track of all summertime physical activity, like hiking, swimming or bike riding, and convert that activity into equivalent miles. The goal is to reach 26.2 equivalent miles, which is equal to a marathon. Then register for the Cherry Creek Schools Fitness Festival on Sat., Sept. 10. Students can participate in either the 5K Run/Walk or the 1K Family Fun Run. Afterward, they’ll receive a medal for completing the Cherry Creek Fitness Challenge!
