Blue Sky Ascent (14.5M) - Jun 28, 2026 | Idaho Springs, CO

Prepare for an extraordinary challenge at the Blue Sky Ascent, America's highest road race, taking place on June 28, 2026, in the stunning landscapes surrounding Idaho Springs, Colorado. This iconic 14.5-mile event dares runners to conquer nearly 4,000 vertical feet of elevation gain on North America's highest paved road, leading to the breathtaking summit of Mt. Blue Sky at 14,264 feet. The journey begins at Echo Lake Campground at 10,600 feet, traversing montane, subalpine, and alpine environments where much of the course rises above the treeline, offering unparalleled views of glacier-cut valleys and an endless horizon of rugged peaks. Keep an eye out for unique spectators, including bighorn sheep, marmots, and mountain goats.

The Blue Sky Ascent, formerly known as the Mt. Evans Ascent, is renowned for its demanding yet rewarding course, with the entire road closed to vehicular traffic for runner safety. Typical race day conditions in late June bring highs around 77°F and lows around 46°F, with a minimal 6% chance of precipitation, though mountain weather can always surprise. Along the challenging climb, runners will find four well-stocked aid stations, strategically placed approximately every three miles, offering water, HEED energy drink, Coca-Cola, Hammer Gel, and various snacks to fuel your ascent.

Beyond the physical test, this race offers a truly unique experience. All finishers receive a custom medal and a long-sleeve, gender-specific race shirt. Achieving a finish time under 2 hours 40 minutes for men or 3 hours for women earns you a coveted "Trophy Rock," a tradition revived from the race's early days. After reaching the panoramic summit, runners are treated to a ride back down the mountain and a tasty post-race meal, ensuring a memorable and inspiring conclusion to this high-altitude adventure.
