Brought to you by Gunnison Trails and presented by Ergon and powered by SRAM. The Original Growler is the primary fundraiser for Gunnison Trails, a Colorado 501(c)3 non-profit organization. Gunnison Trails is dedicated to maintaining and expanding the singletrack experience in the Gunnison area including working toward building the Gunnison to Crested Butte trail. All proceeds from the Original Growler benefit Gunnison Trails. NEW FOR 2017 MORE SINGLETRACK - We have shuffled the course deck and added the new Graceland trails (which your entry fees helped to build), losing the Powerlines Road and the pavement of Gold Basin Road. Apologies, but this additional singletrack just made the Growler a little bit harder! MIDDLE AND HIGH SCHOOL CATEGORIES FOR THE HALF GROWLER AND SUNDAY'S HALF - 8th grade and younger; high school freshman/sophamore; high school junior/senior (each as of fall 2017) KIDS RACES - We are adding kids races on both Saturday and Sunday. From striders to solid climbers and descenders who are not quite ready for the Half Growler, we have the youngsters covered.
