Three age groups competed in the running and biking events.
The five and under group ran around the building and biked through the parking lot, but the older age groups biked through the trails behind the YMCA.
"It's rugged enough that you have to have a little bit or stamina and a little bit or grit to actually make it through the course," said YMCA Aquatics and Youth and Family Director Matt Steingraber.
Some of the kids even trained for the event.
The top three in each age group got awards.
The main purpose of the event was to get kids out of the house and doing something to keep them fit and active.
