In more endurance terms, expert is one level below Pro/Elite and one level higher than Sport and is characterized by riders who are superior to beginners but are not professionals. The Expert class is challenging but achievable. It attracts committed amateur riders who ride frequently and compete regularly. Expert Races tend to have challenging courses and longer lengths than Sport events, but they are set up to be achievable for amateur racers. The Expert level is used by most national mountain bike events to allow riders to enhance their racing experience, bike handling, and overall fitness to upgrade to Pro/Elite levels.
