Rainbow Warrior Dash, Gathering Ideas

To celebrate the end of a full and adventurous summer, we are planning a “mini rainbow warrior dash” for the kids and all their friends.
The kids have seen me run in fun races all summer. They got to stroll along with us in Color Me Rad. They have so much fun at these events that I thought to create an obstacle course suited for children.

Combining the themes from races, we came up with a rainbow warrior dash. The kids and are are in brainstorming mode, making lists and collecting ideas. We have a list of supplies, ideas on how to use them and some great imaginations working on fantastic ways to run, jump, crawl, slide and balance.

Once the kids have their list of ideas, they draw some of the obstacles. Friend A draws a map of the obstacle course. Little K draws a hoola hoop around a boy. Little J works on a logo.

These are some of their ideas:
jump over mountain of toys
hoola hoop as fast as you can
crawl under branches in the deep dark forest
climb over mountain of hay bales
get through a spider web
lazy river, slide with rocks.
crawl through tunnels
jump over pretend fire
lemonade stand

Any other ideas?
