For most sports tourism activities, you don't need any special skills or training.  Being a sports enthusiast is enough to attend events, tours and be a spectator.  However, if you want to participate in sports camps, competitions, or adventure activities, you'll typically need a basic fitness level and familiarity with the sport.  Some may require equipment, proper attire, and in some cases, certifications or permits.  It's best to check with the event or tour organizer about any skills, experience, or gear needed.
