Host a backyard olympics. Throughout the summer, you and your friends can train for and compete in your very own olympics. You can adapt the traditional events to the space you have access to, the equipment you own, and the number of people participating. Your local park can serve as the gymnastics arena Replace golf with frisbee golf Have a free throw contest instead of hosting a basketball game Instead of running a marathon, sign up for a local 5K or fun run Schedule a 3-v-3 volleyball tournament.
