So you’re thinking of taking up trail running in Colorado? Trail running is an excellent way to enjoy our fantastic scenery, and get further into the backcountry, faster. And moreover, you’ll be in great company. More runners than ever before are discovering the joys of getting off-road.
That said, trail running is nothing new in Colorado – the Leadville 100 has been seeing tough runners dash over 100 miles at high altitude since 1983 while the Trans Rockies Run covers 120 miles of the Rocky Mountains over six days. But don’t let all that intimidate you.
Kim Fuller is a Colorado native and Vail resident who has been trail running for years and finds it better for her body than road running.
"Running on trails is so much kinder to your joints than running on the road. While pounding pavement can be convenient from your home or office, the impact is hard on your body and over time you may have to stop running. Seek out the trails in and around your community to find a forgiving surface for training and exploring," says Fuller.
Whether you’re an urbanite looking to make the leap from pounding pavement or a high mountain dweller seeking a new adrenaline rush at altitude, we cover the basics of trail running in Colorado and highlight some of the best trails around the state to get you started.
Before taking your run off-road, you’ll need to invest in a pair of the best trail running shoes to hold up against the rockier terrain. Find out more about what kind of gear you need in your kit in our article on trail running essentials.
Is trail running harder than road running?
In short, yes, trail running is harder than road running. It features more hills and uneven terrain for a start, and in Colorado, there are the added factors of high altitude and wildlife to contend with.
Even if you’re already living here and well-acclimated, making the transition from hiking to running can be tough. The higher you go, the harder your cardiovascular system has to work to get oxygen to your muscles, which means you’ll experience a more elevated heart rate than you would at sea level, and get out of puff faster.
If like most of our population, you live in Denver, the trails you might want to try could be another mile higher if you’re heading up to the high country, so expect a new challenge, but don't be daunted.
"Enjoy the journey! Trail running can offer quite a bit of elevation, especially in places like the Rocky Mountains in Colorado, so it’s okay to hike and run as you achieve your miles," advises Fuller.
Speaking of the steep stuff, another setback when it comes to trail running in Colorado is the average grade of the trails. Lots of the most popular hiking trails in the state gain elevation at a rate of about 1,000ft per mile which is tough enough on a hike. If you’re transitioning from road running, you’ll want to sacrifice your normal pace in return for the joys of climbing.
The final piece to consider is wildlife. If you already live in Colorado and hike regularly, you’ll be no stranger to the occasional bear encounter and you should know your mountain lion and snake safety, but if you’re an urban runner, it’s still worth pointing out that you’re likely to meet – and potentially startle – more wildlife in the backcountry than on Pearl Street, so there is some added risk.
How do I find trail running routes?
The beauty and diversity of Colorado trails make a compelling reason to give trail running a go, according to Fuller:
"There are so many amazing trails in Colorado to explore. It’s rare to be able to run in the high desert, through aspen trees and up to an alpine lake, all within the same region of the same state. You can head out on a weekend adventure and find some off-the-beaten-track terrain in the Colorado wilderness, or just simply step out your door to find premier trail running opportunities that aren’t far from home."
If you’re ready to get into trail running in Colorado, you can run any trail that you hike, theoretically speaking, but lots of your favorite hikes might be a bit daunting to run, and busy, so we’ve gathered some great trails scattered throughout the state that offer stunning scenery without too much elevation gain. We’re not saying they’ll be easy, but these are great trails to get you started.
