Family Adventure Run Info

The adventure run is a short 1 mile course that includes obstacles designed to be a fun diversion for kids on the trail descending from the Challenge Hill.

Yes, everyone needs their own entry.

The obstacles were designed to be a fun challenge for kids ages 5-12. Younger children may find some obstacles too challenging and will need a parent with them to assist. Older children may find some obstacles too easy but are encouraged to participate with their families.

Check out the course map for a complete list and brief description.

In the spirit of liveBIG’s mission and to encourage families to have fun together, the adventure run will not be timed. It’s not a race…….it’s an ADVENTURE!!
