SBT GRVL returns June 27, 2027, with a random-selection window from October 14–31. The 108-mile Black course entry is $295, while the exact 2027 route remains unpublished. We start above 2,000 meters, late-June afternoons can bring fast thunderstorms, and sea-level legs pay an altitude tax. We would train for altitude and exposed gravel without treating the previous course as final.
Better info coming — we're still verifying 3 fields on this race.
Why we'd pick it
- The 2496 m climbing estimate is useful for planning, not a verified pacing number.
- The ballot is closed for this edition.
- A non-racing partner gets a real weekend here — 4/5.
- Race day usually sits 9.8–26.7°C, about 15% chance of rain.
The course
The 2027 courses are not published yet. The current planning placeholder follows the 2026 one-day format: Black at 108 miles, Blue at 73, Red at 53, and Green at 25 on Routt County gravel. Steamboat starts above 2,000 meters, so altitude remains the reliable hardship; the stored 2,496-meter gain and 3,050-meter high point must be replaced when the route appears.
Difficulty and PR scores
