Full Race Rules

The following rules govern the Full Montane Winter Spine (Spine Race) 2027. These rules must be followed at all times during the event, both on the course and at each checkpoint. Spine Races are non-stop winter mountain marathons and must be treated as serious undertakings.

Due to the potential for adverse or extreme weather conditions, you are responsible for your own safety on the trail and at all checkpoints. You must be in good enough physical condition to complete the race in your chosen category within the allotted time and possess the necessary skills to navigate effectively and manage emergency situations in mountainous terrain during the winter.

In addition to accepting the Race Rules and Terms & Conditions of entry, it is required that you digitally sign/agree to the participant waiver and complete the medical questionnaire prior to the start of the race. By joining the race, you accept the Race Rules and Terms & Conditions of entry.
