Know Before You Go
- Booking model
- Most indoor tracks sell timed sessions (10-15 min) at $20-35 each, with packages of 2-3 races discounted. Reservations strongly recommended for evenings and weekends.
- Kart speed
- Adult karts top out at 35-50 mph on indoor tracks — quick enough to feel fast in a concrete-walled facility. Junior karts run slower with rev-limiters by age tier.
- Minimum age & height
- Most venues require drivers to be 48-58 inches tall (kid karts) or 13+ for adult karts. ID is sometimes required. Closed-toe shoes are universally required.
- League nights
- Many tracks run arrive-and-drive league seasons (8-12 weeks) for $300-600 with points championships. A great way to learn racecraft without owning a kart.
- What's provided
- Helmets, neck braces, and head socks are included. Some tracks also rent driving suits. Bring or buy nothing — you can show up in jeans and a t-shirt.
