What Ages Can Race

Karting is for virtually everyone.

At Iron Rock, karters can start as young as five years old in the Kid Kart class. This is run as a demonstration-only class, but it teaches young drivers the skills they need to compete in trophy and purse races in later years.

Most organized forms of kart racing, local and national, begin serious racing at age eight. Typically, a class is formatted for eight to 12 year olds, with the next common grouping being racers aged 12 through 15. Drivers are usually categorized as senior class once they reach 15 or 16 years.

Iron Rock offers several over-35 classes, and it's not uncommon to find kart racers in their 60s.
