The lay of the land
The adventure race calendar in California is busiest in February, August, and September, with races most often in San Diego and Santa Rosa.
Adventure racing combines several disciplines — trekking, running, mountain biking, and paddling — with navigation by map and compass between checkpoints over a single course. Events range from a few-hour sprint to multi-day expedition races, and are commonly raced in teams.
Because navigation is part of the challenge, route choice and decision-making matter alongside fitness, and there is not always a marked course to follow. The exact disciplines, distances, and team-size rules vary by event.
