Concussion Test Required for Pro Classes

In recognition of the potential harm from undiagnosed neurocognitive injuries, riders competing in the Pro classes will be required to complete the online ImPACT neurocognitive concussion test and upload proof of completion prior to competing in any further events.

GNCC Racing is fortunate to have Dr. Marc Tanner’s Safety On-Site Medical Service (SOS) at the GNCC events to manage this concussion protocol and encourages all riders over the age of 12 at all levels of competition to complete the test.

Accordingly, Section A.8 of the 2025 GNCC Pro Competition Rules is amended as follows:

e. Concussion Test: Effective immediately, in order to compete in the XC1, XC2, WXC and 4x4 Pro classes riders must have proof of completion of the ImPACT Concussion Management Test within two years of the date of competition. Any racer who sustains a known concussion or loss of consciousness during an event or otherwise shall be suspended from further competition until the racer can provide proof of compliance with the ImPACT Concussion Management program as determined by the GNCC Medical Director. Upload proof of completion to the GNCC Pre-Registration Rider Profile.
