The 10-kilometer out-and-back loop is repeated multiple times for longer distances such as the 50K and 100K races, providing ample opportunities to see familiar landmarks in new light under changing skies. Runners will find themselves navigating through diverse terrains—from smooth asphalt bike paths to rugged dirt trails—each segment adding its own character and challenge.
Aid stations are strategically placed every five kilometers along the course, ensuring that runners have access to essential supplies like water, energy gels, and other hydration options necessary for such long-distance runs. Participants can also leave drop bags at the start line to be passed on specific intervals throughout their journey, allowing them to carry only what they need during each loop without worrying about missing crucial items back home.
In preparation for the event’s unique course conditions, runners should anticipate a range of weather scenarios typical for Southern California in June.
