Additional Race Info

The race courses will be well marked with orange plastic ribbons with black polka dots and reflective medallions. Trail junctions and turns will be well marked with laminated signs. In addition, blue & white checkerboard plastic flagging will be hung to designate non-race or “WRONG WAY” trails. All runners are responsible for understanding the layout of the course. Please familiarize yourself with the course maps on our website prior to race day and/or download the gpx file to your phone.

We will have our MedStar Solutions medical staff based at the start / finish headquarters to assist with first aid onsite. We reserve the right to pull you from the race if medical officials deem it necessary.
NOTE: Please do NOT call 911 in a medical emergency. Our medical team is highly trained and understands the terrain and driving access points. Please call the race day number and they will dispatch immediately.

MedStar Solutions Race Day Number: 480-269-4126
