A popular and highly competitive event, run in the flat desert east of San Diego, CA.  The course runs on an 18mi, mostly-flat loop, changing to a shorter loop for the last portion of the available time.  The event often fills, so registration as early as possible is advised. (Note, while the name of this event includes the wording as world championship, it is not sanctioned as such by WUCA and the bonus points associated with that status do not apply.)
