September 8th will be our first year for our High (Middle) School Invitational in our Platte River Rumble Series. We are estimating around 2,400 runners and 4,000 spectators for this event. With this kind of traffic, we will need each and everyone of you to help make this a success! We thank you in advance and look forward to making this event one to remember.

All volunteers will be provided with a shirt and we ask you wear black pants/shorts and comfortable outdoor shoes. Volunteer parking information will be sent closer to the event.
