WEATHER POLICY In the event of inclement weather, the start time of this event may be delayed by up to 1 hour. Past this time, the event course may be shortened or altered to protect the participants. If conditions turn unsafe, the event may be cancelled. Event changes and cancellations are at the discretion of the Race Director. We always strive to produce a full and safe sporting event, but sometimes the weather conditions can affect those plans. Considerable amount goes into planning a sporting event and we do so with the best intentions. Unfortunately, no one can control the weather and race directors are not the exceptions. Our goal is to always produce a full event as scheduled and only modify these plans due to safety concerns some of which can be caused by weather conditions.
