The past year has been unlike anything we have ever experienced so we sincerely hope you and your family are safe, healthy and well. We hope you have found ways to stay positive, active and hopeful during this time.

We appreciate your continued patience as we navigate the uncertainty surrounding the return of large-scale athletic events.

While this was an incredibly difficult decision, we do believe that it is the right one to protect the safety and best interest of all involved.
