Steamboat Marathon, Half & 10K

The Steamboat Marathon has run on the first Sunday of June since 1982, and the 2026 edition on June 7 is its 45th consecutive year. The race includes marathon, half marathon, and 10K distances, all running alongside the Elk River through the emerald green pastures of Country Road 129 with the snow-capped Rocky Mountains surrounding the course. The full marathon starts at Hahns Peak at 8,128 feet elevation and descends to downtown Steamboat Springs at 6,728 feet, a point-to-point course structure that produces the combination of mountain scenery and net-downhill running physics that has earned it consistent recognition. The course holds its position as a certified Boston Qualifier and has been ranked among the Top 10 Destination Marathons in North America. The 10K begins at 7:30 a.m. from 5th Street in Steamboat Springs; the half marathon and full marathon depart on staggered schedules, with all courses closing at 1:00 p.m. Registration is available at steamboatmarathon.com, with entry costs ranging from $40 to $100 depending on distance and registration timing.

Race Director Paul Sachs, who has guided the event across its recent editions, describes the Steamboat Marathon’s persistent appeal as rooted in its proportion: large enough to attract serious competitive runners from across the country, small enough to maintain the hometown feel that makes every finisher count in a way that major metropolitan marathons structurally cannot. The vendors expo and race activities that accompany the event through the downtown district transform Steamboat Springs’ Lincoln Avenue corridor into an accessible community celebration for family members and supporters who are not running, with street closures and traffic detours coordinated to protect both the course and the town’s normal commercial function.

Steamboat Springs Beyond Race Day

Steamboat Springs’ summer identity is built around a dual inheritance: the Yampa Valley’s agricultural ranch culture, which preceded the ski resort by a century, and the outdoor recreation industry that the ski resort catalyzed in the 1970s. The Steamboat Ski Resort’s summer gondola carries riders to the 10,568-foot summit of Mount Werner for hiking access and views that the valley’s elevation alone does not provide. The Yampa River Core Trail, running through Steamboat’s commercial center, connects the race’s finish-line area to the river kayaking features and the park system south of downtown. The Strings Music Festival, Steamboat’s summer classical and chamber music series, runs through July and August with performances at the Strings Music Pavilion west of town that have attracted significant national and international attention.

Good to Know
High-altitude racing at Steamboat’s starting elevation of 8,128 feet demands acclimatization planning for athletes arriving from sea level. Arriving 48 to 72 hours before race day and maintaining hydration through the adjustment period is the standard preparation recommendation for runners traveling from below 5,000 feet. The net-downhill course produces a quad-loading profile that catches some runners by surprise in the final miles; account for it in pacing strategy regardless of how easy the first half feels.

Steamboat Lake and the Water Setting

Steamboat Lake, 25 miles north of Steamboat Springs in Routt County on County Road 129, sits at 8,000 feet in a mountain basin formed by the same geological processes that shaped the Hahns Peak volcanic landscape above it. The state park reservoir offers sailing, kayaking, and rainbow trout fishing in a setting remote enough from the resort corridor to carry a distinctly quieter character than the Yampa Valley’s summer activity.
