Junior Qualification for Super Track and Challenge GP Races

Racers between the ages of 14 and 18, who may be too old or too experienced for our Junior Karting League, can now qualify to participate in Challenge GP and Super Track races. In order to have the opportunity to race with the best, individuals need to show us that they can hang with the best! Any racer between the ages of 14 and 18 who has an XP Live Score at or above 1,000 points can participate in Super Track and Challenge GP go kart race league events. We have created this new rule due to the high demand from teen drivers (and their parents) who have shown that they have the skills to compete. Our Challenge GP and Super Track races are fun and unique events, but are also highly competitive; it takes a certain amount of track experience and maturity to race against the top K1 Speed racers, thus our qualifying system to ensure that the environment is safe for everyone on the track.
