NEW TO BMX? YOU’RE IN THE RIGHT PLACE.

FIRST LAP.
BIG SMILE.

You don’t need a race bike or racing experience. Your first race is free, and free loaner bikes are available by size.

01

Pick a race day. Arrive during sign-ups and tell registration it’s your first time.

02

Gear up. Bring a helmet, long sleeves, long pants, and closed-toe shoes. Bring your bike or ask about a loaner.

03

We’ll get you rolling. Our volunteers will help with registration, bike checks, and getting on the track.

Plan your first visit
What should I know before I come?

Remove pegs, kickstands, and reflectors from your bike. Check in with registration before riding so our volunteers can review equipment and trial membership options. Riders under 18 should come with a parent or guardian. Loaner bikes depend on size and availability.
