Safety is our number one priority. A race, run, or other event may be canceled, delayed, suspended, or postponed, or the course may be modified in the event of threatening weather conditions that could make the run unsafe for participants. Such threatening weather conditions may include: lightning, heavy rain, wind/tornadoes, extreme heat, ice/snow, or other major weather conditions. Extreme heat is defined as a heat index that meets or exceeds 105 degrees Fahrenheit at the time of the event or run. In the event of visible lightning or audible thunder, at least 30 minutes must pass before outdoor events commence or resume. It is up to the race director or run leader to determine whether the conditions are threatening and communicate any decision to alter the event or run to participants.
