SBT GRVL® presented by Wahoo, a global endurance and lifestyle event bringing together gravel cycling, trail running and mountain-town culture, announced that registration for random selection is open through October 31 for its June 25–27, 2027 event. The weekend will welcome an expanded field of 3,000 riders, bring back age-group podiums on the Red and Blue courses and introduce a new 20K trail run race and SBT DBL BLK two-day run-bike challenge.

Following the success of the 2026 event, Routt County commissioners unanimously approved the increased rider capacity and age-group competition for 2027. Alongside the growing SBT TRL run race lineup, these additions give athletes more ways to compete on Steamboat’s signature “champagne gravel” roads and Emerald Mountain trails.

Four Signature Gravel Courses, Age-Group Podiums Return

Sunday, June 27, will feature four course distances through Routt County: Black (108 miles), Blue (73 miles), Red (53 miles) and Green (25 miles). Age-group podiums return to the Blue and Red courses, joining those on the Black course to recognize amateur athletes across three distances.

The 2027 SBT GRVL p/b Wahoo courses return to the routes you loved in 2026, showcasing the rugged beauty and remote landscapes of Routt County. Riders and racers will encounter familiar sections from years past while experiencing some of the finest and most scenic gravel roads in the world. The Blue Ride and Black Race courses feature plenty of climbing, along with steep, loose sections that will test you both physically and mentally.

2027 SBT GRVL® Black Race Course | 108 Miles | 8,189 Feet | 70% Gravel

The signature course returns for professional and amateur racers looking to compete amongst each other and against the clock. Our most challenging route for 2027, the Black Course will feature separate starts for Elite Men/Open, Women and Amateur categories as well as our rolling enclosure/safety bubble at the front of each group. Our $22,000 prize purse will be split evenly between the top Elite Men’s/Open and Women’s Elite fields, GRVL® Femmes racers will compete for a cash prize, and podium prizes await the fastest amateurs in their age groups*. Racers will roll out from Yampa Street in downtown Steamboat, climb Zipp Cow Creek before ascending toward Trout Creek and Wahooligan Pass on their way toward Hayden before taking a partial lap of the 2025 race course and returning to descend Zipp Cow Creek and finishing on Yampa Street.

For 2027 outside/team nutrition support will once again be available at the Hayden Gun Range aid station and spectator zone.Time cutoffs will be strictly enforced for Blue and Black courses and riders not averaging 10mph (Black) and 8mph (Blue) elapsed time will be re-directed to a shorter course.

2027 SBT GRVL® Blue Ride Course: 73 Miles | 5,843 Feet | 65% Gravel

Don’t want to tackle a gravel century but still want an epic day riding and racing on the rural roads with your friends? Our Blue Course is a fan favorite that incorporates the most dynamic elements of the Black Course but cuts back to Steamboat after Wahooligan Pass instead of rolling toward Hayden. The course is spectacular, and if you’re experiencing déjà vu it’s because we taking you in a reverse direction on some of our favorite sections from previous year’s Blue and Black Courses. New for 2027 we will be offering age group prizes and podiums.

2027 SBT GRVL® Red Ride Course: 53 Miles | 4,198 feet | 52% Gravel

The shortest “race” distance, this 53 mile route now features age group podiums as well as stunning gravel, fast paved sections, 3 aid stations, and hours of entertainment. The perfect half century, this course splits its time between our famous champagne gravel and some rolling paved hills in ranch country, but will keep you on your toes by throwing in our famous and chunky Cow Creek on your way out and back to the finish.

2027 SBT GRVL® Green Ride Course: 25 Miles | 1,822Feet | 31% Gravel

Your gateway to GRVL®, the 2027 Green Course runs in the reverse direction of our 2026 route, and is our most beginner and e-bike friendly ride of the day. This 25 mile course starts on the pavement, climbs our infamous Zipp Cow Creek section, then descends the champagne gravel of FNL CLMB. From there riders will ascend CR 33 before descending back into town . Don’t be fooled by the distance, this bite size course will whet your appetite but provides plenty of challenge with long scenic climbs at an altitude of 7,000+ feet.

GRVL® Femmes New Prize and Coaching

Founded in 2025 to create a welcoming, empowering environment for amateur female cyclists, GRVL® Femmes returns for its third year in 2027. In the spirit of Zwift Watch the Femmes, Zwift will introduce a new prize: one randomly selected GRVL® Femmes team will receive a travel stipend and trip to L’Étape to ride the Tour de France Femmes course and watch the race.
