America’s premiere six-day mountain bike stage race delivers 220-240 miles of backcountry singletrack with roughly 40,000 feet of vertical gain across stages ranging from 35-50 miles each. The event maintains exceptional quality with a 400-rider field limit, drawing participants from over 25 countries and 40 states annually.

Each stage follows a cloverleaf format starting and finishing within a mile of downtown Breckenridge, beginning daily at 8:30 am. Course designers crafted routes around a simple question: “What big rides would we want to tackle with six of our best friends and most of the day?” The result captures the essence of mountain biking dreams through long, rhythmic climbs and exhilarating descents.

Stage highlights include Pennsylvania Creek’s heart-pounding 35.7-mile opener with 5,700 feet of climbing, and the Colorado Trail’s epic 42.5-mile journey featuring recent improvements that eliminated sun-baked gravel sections. The Circumnavigation of Mt. Guyot crosses the Continental Divide twice over 40.5 miles, complete with Onesie Wednesday dress code and Skittles hand-ups at French Pass. Stage 5 condenses the challenge into 24.6 miles using a 10-rider time trial format, while the Gold Dust Trail finale features PBR hand-ups and scenic private property access.

The competitive structure includes $10,000 in prize money split evenly between pro men and women, with awards presented five-deep across all categories including 6-day Solo, 6-day Duo teams, and 3-day Solo options. Multiple aid stations per stage provide strategic refueling opportunities throughout the demanding backcountry terrain.

The atmosphere blends serious racing with mountain town camaraderie, emphasizing big rides with friends against Breckenridge’s stunning alpine backdrop.
