Your Junior Bike Week event registration fees directly support the following efforts: 

• Provide the opportunity for juniors to participate in a festival that exists to celebrate KIDS ON BIKES.  
• To support the future of our sport by creating lifelong memories with our children at Junior Bike Week so they are able to experience the genuine magic that can only be found riding bikes with friends.
• As a fundraiser for the Crested Butte Development Team, Junior Bike Week revenue helps our nonprofit organization offer the safest, highest quality, progress-based programming available for youth ages 2-18 at the most affordable cost possible.
