Fueling & hydration
Aid stations appear roughly every 2 miles with water and sports drink. The smooth, gently downhill rhythm makes a fixed gel schedule simple; drink early, as Southern California sun can warm the later miles.
Weather
Early-May Orange County mornings are mild and often marine-layer cool at the coast (50s–60s°F), warming inland through the race — an early start keeps conditions fast.
