In an attempt to simplify categories and accommodate the growing number of younger racers, slight alterations to the categories have been made based on last year’s races and participant feedback. In the adult series, the vet, master and grand master titles have been dropped, however the age and skill designations have not changed. An 18 & under sport category has been added, allowing younger competitors to race longer and more challenging courses with their peers. Finally, significant changes have been made to the Larkburger Youth Series categories, which will now offer beginner and sport categories for all age groups, giving kids more options to race at their comfort and ability level. A full list of categories and rules is available at www.vailrec.com.

Short track races cost $15 for preregistered adults and $20 on race day. Youth short track racers can preregister for $5 per race or $7 on race day. Discounted series registration is available for both youth and adults. For the Athletic Club at the Westin Mountain Bike Series, individual adult races cost $26 for preregistration or $37 on race day. Racers can also register for the entire race series for $155 by May 12 or $170 after May 12. Teams of up to 25 riders can compete for the overall series title as well. The Larkburger Youth Series (ages eight to 18) costs $60 for the entire series, $10 to preregister for individual races or $15 on race day.
