This route was planned by komoot.
The Trail 401 Loop is a challenging jog, and komoot estimates it takes approximately 2 hours to complete the 14.1 km route. This duration can vary based on your fitness level and how often you stop to enjoy the views.
The terrain is diverse, featuring mostly smooth, fast singletrack ideal for running. However, be prepared for sections that can be chunky, rutted, or include rockfall, requiring careful footing. The route starts with a significant climb up Schofield Pass Road (gravel) followed by an even steeper 1.3-mile ascent on singletrack. You'll also encounter technical sections weaving through trees with rocky and rooty patches, and narrow areas with steep drop-offs.
The trail offers stunning alpine scenery throughout. You'll be treated to sweeping views of the Elk Mountains, including the Gothic Valley and Mount Crested Butte. Highlights include passing by Emerald Lake and traversing through vibrant wildflower-strewn meadows in late July, or golden aspen groves in October. You'll also experience areas dense with unique flora like shoulder-high skunk cabbage.
No, the Trail 401 Loop is generally considered difficult, especially for the full loop. It involves substantial elevation gain (around 500 meters according to komoot, but research suggests closer to 700 meters) and reaches high altitudes (up to 11,350 feet). The sustained climbs and descents, combined with the altitude, make it a demanding experience best suited for intermediate to advanced joggers.
The best time to jog the Trail 401 Loop is typically from late June through early October. Late July is ideal for experiencing the vibrant wildflower meadows, while October offers spectacular golden aspen groves. Always check local conditions, as high-altitude trails can retain snow into early summer.
The Trail 401 Loop is located near Crested Butte, Colorado, within the Gunnison National Forest. The route typically starts with a climb up Schofield Pass Road. Specific parking details can vary, so it's advisable to check current local information for trailhead access and parking availability before your visit.
Yes, the Trail 401 Loop is generally dog-friendly. However, as it's located within the Gunnison National Forest, it's crucial to follow all forest regulations, which typically include keeping dogs on a leash and cleaning up after them. Be mindful of wildlife and other trail users.
The Trail 401 Loop is located within the Gunnison National Forest. Generally, there are no specific permits or entrance fees required for day use on trails within the National Forest system. However, always check the latest regulations from the U.S. Forest Service or local ranger district before your trip, as rules can change.
Yes, the route incorporates sections of several other paths. Notably, it follows significant portions of the 401 Trail and Trail Riders 401 Trail. You will also briefly pass through sections of the ADT - Colorado C - Q - Seg 5, Bellview Road, Emerald Lake Picnic Ground Road, Rustler Gulch Road, Schofield Trail, and Paradise Basin Road.
While the full loop is rewarding, some find the second half, which involves more climbing, less enjoyable. If you're looking for a slightly less strenuous but still scenic experience, consider an out-and-back option on the most celebrated sections, or be prepared for the sustained effort required to complete the entire loop. Starting early can help avoid afternoon thunderstorms and secure parking.
