Overview SBT GRVL is a gravel cycling weekend in Steamboat Springs, Colorado, run on the county roads of Routt County. Steamboat local and former pro racer Amy Charity founded it, and Wahoo is the presenting partner. Sunday holds four courses, from a 25-mile intro ride to the 108-mile Black race, and the days before add a downtown expo, a hill climb and a trail run. Brands can start with a single expo booth or take a two-year category partnership with a named activation. On site The expo fills Yampa Street for two days with 80-plus booths, packet pickup, panels, yoga and a toddler race, and vendors can sell on site. Friday night is the MTN CLMB at Steamboat Resort: head-to-head hill-climb heats, a costume lap and a free concert at the base. Saturday brings the SBT TRL trail run at Howelsen Hill with 20K, 12K and family 5K distances. On Sunday the Black course runs behind a rolling enclosure with an equal purse for elite men and women, while the Blue, Red and Green courses cover 73, 53 and 25 miles. Partners also get a sponsor party on Thursday night. Audience About 3,000 riders come from all 50 states and 16 countries, and some 7,000 spectators and visitors join them. Riders range from 8 to 82, about 27% are women, and Colorado sends the most, ahead of California, Utah and Texas. Nearly half are riding SBT GRVL for the first time. Riders give the event a Net Promoter Score of 91. Talent and Influencers Elite men and women race the Black course next to amateurs, and age-group podiums run on the Blue and Red courses. The GRVL Femmes team challenge brought 28 teams and more than 800 women to the start line, and 24 riders came on scholarship. Black Girls Do Bike NYC, Mile High 360, Outride and All Clubs LA receive guaranteed entries for riders who are under-represented in cycling. Seventeen media crews and photographers cover the weekend, and Outside and GRVL Films have made documentaries about the race. Track record Entries go by lottery because demand runs past the rider cap, and Routt County voted unanimously to restore the 3,000-rider field.
