Set on a 4,000-acre working cattle ranch on the northeastern shore of Oahu, this 13.1-mile course winds through dense jungle, verdant pastures, and steep mountainsides that give way to ocean views. Don’t let the name fool you: Though it’s called a World Championship, you don’t need to qualify for this event. It’s merely the last race on X-Terra’s 70-stop world tour. The half marathon is the main event, but there is also a 5K and 10K, as well as a family adventure walk.
