For Individuals, For Families! Where no one rides the bench!

Riding at County Line BMX
The track is open to the public on non race days, free of charge, when weather permits. Bike helmets required.  Motorized vehicles including RC cars are NOT allowed on the track.
Please note: the gates will be locked when any part of the BMX track is too wet to ride. It can take several days of completely dry weather for the track to dry after a rain/snow. If you have any questions, or to find out if the gates are open, call 303-798-7515.

Racing at County Line BMX
ALL ages and abilities welcome! (We have riders 3 years and 60 years and EVERYTHING in between!)
USA BMX racing is a sport of youthful achievement and the American family. While the young boy or girl BMX racer develops skills at an individual pace, they are learning about winning, losing and trying again. The racer's family learns that time spent together in support of the racer and the individual achievement is quality time well spent. It is the duty of the USA BMX to establish the rules of racing that provide fair competition and fun family entertainment for all of its 70,000+ members. Visit
