Running the Rio Grande Trail in Aspen, Colorado

The Rio Grande Trail isn’t just a path—it’s a runner’s dream. Stretching over 40 miles from Aspen to Glenwood Springs, this multi-use trail offers a seamless mix of breathtaking scenery, gentle gradients, and a quiet escape from the hustle of everyday life. For runners, the section near Aspen is particularly magical, blending the town’s charm with the wild beauty of the Roaring Fork Valley.

Your run begins just outside downtown Aspen, where the trailhead invites you to lace up and take that first stride. The path quickly transitions into a peaceful retreat, flanked by aspen groves and towering evergreens. The gentle rustle of leaves and the steady murmur of the Roaring Fork River create a natural rhythm that makes running here feel effortless.

The trail’s compact gravel surface is easy on the joints, while its slight downhill slope keeps the pace brisk without being taxing. As you glide along, each turn reveals something new: a glimpse of snow-dusted peaks, a bridge spanning the sparkling river, or a wildflower-filled meadow buzzing with life in the warmer months.

For shorter runs, the stretch from Aspen to Woody Creek is perfect. At just under 8 miles one way, it offers enough distance for a challenge while keeping you connected to the valley’s most scenic sections. Ambitious runners can tackle longer routes, weaving through the valley as the trail meanders toward Basalt, Carbondale, and beyond.

By the time you loop back to Aspen, lungs filled with crisp mountain air and legs pleasantly tired, you’ll understand why the Rio Grande Trail is beloved by locals and visitors alike. It’s not just a trail—it’s an invitation to move, breathe, and connect with the natural beauty of the Rockies.
