Volunteers Needed!

Putting on an event like this would not be possible without the support of volunteers.  Parents, please consider signing up to volunteer. This is a great way to give back and see your athlete on the course. This is also a good volunteer opportunity for teenagers. If you would like to help out and support these fantastic youth athletes, we’d love to have you on board.  There are a variety of assignments to be filled.  Volunteer registration is now open.
