ASPEN TO MT. CRESTED BUTTE
August 31, 2025
The Grand Traverse Mountain Bike is no ordinary mountain bike race. It is a point-to-point from Aspen to Crested Butte, Colorado. In total, bikers travel 40 miles across the Elk Mountains with over 6,800′ of elevation gain. The course starts with a 3000′ ascent up Aspen Mountain before continuing deep into the Elk Mountains. This mountain bike race is not for the faint of heart.
The Grand Traverse is operated as a fundraising event for Crested Butte Nordic, a 501(c)(3) recreational non-profit organization.
Triple Crown and priority registration for the 2026 event will open at midnight on Monday, November 17th. General registration for the ski, run, and bike opens at midnight on Monday, December 1st.

POLICIES, DATES, and DEADLINES
We do not offer race entry refunds or transfers between participants.
We strongly recommend purchasing Racer Protection at registration. Racer Protection covers your registration purchase in the event that you cannot attend the event due to unforeseen circumstances (injury, illness, loss of a job, etc.). You can find more information on Racer Protection on the Run Sign Up registration page.
We will operate a traditional waitlist. As numbers allow, the Race Director will contact waitlisted teams with an event registration link. The waitlist and registration will close about two weeks prior to race day.
THE COURSE
This is a 40-mile point-to-point event. If you preview any part of the course, be prepared for a long day out in the alpine.
MANDATORY GEAR
Bikers are required to carry the following gear:
waterproof windshield with hood
hat or buff
gloves
helmet (must be worn at all times)
The listed gear are the essentials required to race. However, every athlete should exercise their own backcountry sense as to what supplementary gear they may wish to pack.
A Colorado Outdoor Search and Rescue Card (or a current Colorado hunting/fishing license) is required to participate in any Grand Traverse race. You will have to show proof of purchase at bib pick-up. Do this ahead of time and save yourself the headache. This $5 supports Colorado Search and Rescue and offers great protection in the unlikely case of a backcountry rescue.

FAQs
-
As a small nonprofit, Crested Butte Nordic depends on early registrations to plan races. Most event costs—like permits, staffing, contractors and insurance—are paid upfront, regardless of attendance. Due to these fixed expenses, we can’t offer deferments or refunds. We strongly recommend purchasing the racer protection during registration. Learn more about racer protection here.
-
No. we do not allow race entry transfers between participants, as doing so bypasses our official waitlist and compromises the fairness of the registration process.
-
The run requires a waterproof windshield with hood, hat or buff, gloves, and a CORSAR card or current CO hunting or fishing license. The bike requires the same gear as the run and a bike helmet. Every athlete should exercise their own backcountry sense as to what supplementary gear they may wish to pack.

Always follow course markings on race day rather than relying on your GPX file.
