Colorado’s Top 10 Trail Runs

Blooming flowers and chirping birds can only mean one thing — it’s running season. With 300 days of sunshine a year, no one can deny Colorado is one of the best places on earth to be a trail runner. From casual jogs to gnarly mountain climbs, here are ten of our favorite trail runs throughout the state.

Mesa Trail, Boulder

A quintessential Boulder run, the Mesa Trail is a great out and back, connecting Chautauqua Park with Eldorado Canyon Road. Soak up striking views of the Flatirons to the west, while the horizon stretches as far as the eye can see to the east. You can also do it as a point-to-point with a shuttle. Either way, end with a meal at the Chautauqua Dining Hall.

Spring Creek Trail, Steamboat Springs

Leaving right from downtown Steamboat, the Spring Creek Trail has just about everything you could want out of a trail run. Single track, aspens, wildflowers, and rock formations, it’s no wonder this is one of the more popular trails in Steamboat.

Turquoise Lake Trail, Leadville

While the trail alongside Turquoise Lake is relatively flat, running at almost 10,000 feet is always a challenge. It is, however, a great place to acclimatize and enjoy a pleasant waterfront trail along one of the largest bodies of water in Colorado. Just ten minutes outside of town, it’s typically done as an out and back so you can make it as long or short as you please.

Distance: 12.8 miles (out and back)

Elevation Gain: 133 feet

Difficulty: Mild

Trailhead Info: Park at the Molly Brown Campground off County Road 4 on the eastern shore of the lake

Crag Crest Trail, Grand Mesa

It’s time to hit one of the most scenic runs in Colorado. Let it out atop Grand Mesa, the world’s largest flat-topped mountain. Below treeline, the trail winds through lakes and scenic wildflowers. The whole run sits above 10,000 feet so it can be difficult for out-of-towners who aren’t yet acclimated.

New Santa Fe Regional Trail, Colorado Springs

Enjoy incredible views of Pikes Peak on this 20-mile pathway that connects Palmer Lake and Colorado Springs. Seven miles of the trail wind through Air Force Academy grounds, making it a unique way to see the place. Run north to south and enjoy a gradual descent all the way down.
