All League and Club racers must have an X1 Outdoors Competition License to participate. Call 781-228-2050 for complete league details.


Confidence ... Sportsmanship ... Coordination ... Responsibility ... That's what kids get from Racing!

Most of today's professional racing stars - Jeff Gordon, Juan Montoya and Dale Earnhardt Jr., to name a few - started their careers by developing skills at an early age through kart racing.


X1 Outdoors, in conjunction with X1 Boston, offers racing opportunities for kids. Starting with Junior Novice Academies at X1 Boston that teach the basics, then Advanced Academies at X1 Outdoors to elevate their competition. Once they complete an Academy, kids are eligible to join a Junior League to compete against other racers of similar age, size and ability.

Introduce a child (age 7 to 17) to the same opportunity as the motorsport stars. Racing teaches:

  • Sportsmanship - a genuine respect for the other drivers (on the track…or the road.)

  • Coordination - a sense of timing and the ability to plan ahead

  • Self Reliance - Once the green flag drops…they're on their own

  • Competition - racing hard, playing hard, competing hard…and fairly

  • Responsibility - a sense of awareness and concern for the safety of others

  • Pride & Accomplishment - whether they finish first, or last, knowing that they did their best. …who knows…maybe they'll be the next star behind the wheel!
