Running

The Grays Peak Trail offers a difficult jogging experience through diverse alpine terrain. You will start with gradual paths winding through meadows and an alpine valley, enjoying the vibrant wildflowers in summer. The route then becomes steeper, leading you through rocky sections and scree as you approach the saddle between Grays Peak and Torreys Peak. This challenging 13.4 miles (21.5 km) route involves a significant 4323 feet (1317 metres) of elevation gain. Expect to complete this high-altitude workout in about 3 hours and 38 minutes, reaching panoramic views of the Rocky Mountains from the summit.

When planning your visit, be aware that the access road to the upper trailhead, Stevens Gulch Road, can be quite rough. A high-clearance 4WD vehicle is often necessary to reach the starting point. Snow patches can linger on the trail into mid-June or even July, so be prepared for varying conditions depending on the season. To avoid crowds and the common afternoon thunderstorms, especially on summer weekends, an early start is highly recommended.

This route is notable for its high-altitude environment, offering a direct path to one of Colorado's prominent 14ers. From the summit of Grays Peak, you are rewarded with expansive views across the Rocky Mountains and the Continental Divide. You can also spot neighboring peaks, including Torreys Peak, making it a classic high-country adventure. The diverse terrain, from meadows to rocky scree, showcases the varied ecosystems of Arapaho National Forest.

Grays and Torreys Winter/Lower Trailhead

Highlight • Parking

There is a packed gravel parking lot here off of I-70 with access to Stevens Gulch Road, an easy gravel road that takes you up around three miles to the summer trailhead for Grays Peak. This road is part of the Continental Divide Trail.

There is plenty of parking at the trailhead and public restrooms are available. The CDT crosses a scenic bridge and climbs up Grays Peak via a gravel road / doubletrack the entire way. If you are headed up Torreys, take the spur trail from Grays — not the Kelso ridge trail (the first turnoff). The Kelso ridge trail is treacherous class 3 mountaineering and not at all runnable. The other trails from here are all relatively nontechnical and very rewarding.

Grays Peak

Highlight • Summit

Grays Peak is one of Colorado's famous 14ers and one of the easier ones to summit. If you hike along the iconic Continental Divide Trail (stretching from Mexico to Canada), this mountain is directly on your route. As with all mountains in this area: Keep an eye on the weather. Thunderstorms in the afternoon are very likely during the summer months, so start your hike early. And since you are already here: With Torreys Peak, there is another 14er just around the corner.

Frequently Asked Questions

How do I get to the Grays Peak Trailhead and where can I park?

The primary access point is the Stevens Gulch Road, which leads to the Grays and Torreys Summer Trailhead. Be aware that Stevens Gulch Road can be very rough and often requires a high-clearance 4WD vehicle. If you don't have suitable transportation, you might need to park further down at the Grays and Torreys Winter/Lower Trailhead, which adds significant mileage and elevation to your trip. Arriving early, especially on summer weekends, is highly recommended to secure a parking spot and avoid crowds.

Are permits or fees required to access the Grays Peak Trail?

The Grays Peak Trail is located within the Arapaho National Forest. Currently, there are no specific permits or entrance fees required for day use on this trail. However, it's always a good idea to check the official USDA Forest Service website for the most up-to-date regulations and any potential changes, especially concerning parking or group sizes. You can find more information at usda.gov.

Is the Grays Peak Trail dog-friendly?

Yes, the trail is generally dog-friendly. However, it's crucial to keep your dog on a leash at all times to protect wildlife and ensure a safe experience for all trail users. Given the high altitude, rocky terrain, and potential for snow, ensure your dog is conditioned for such an outing and carry extra water for them.

What is the best time of year to jog this trail?

The best time to jog the Grays Peak Trail is typically from late June through September. During this period, the snow has usually melted from the higher elevations, and wildflowers are often in bloom in the lower sections. An early start is essential to avoid afternoon thunderstorms, which are common in the Rockies, and to minimize exposure to the sun at high altitudes. Winter jogging is possible but requires specialized gear, experience with snow travel, and awareness of avalanche conditions.

What is the terrain like on the Grays Peak Trail?

The trail starts with a relatively gradual dirt and rock path through meadows and an alpine valley. As you ascend, the incline becomes significantly steeper, featuring numerous switchbacks. Expect rocky sections, loose stones, and scree, especially at higher elevations and around the saddle between Grays and Torreys Peaks. Snow patches can persist into mid-summer, potentially requiring poles. The route follows parts of an old mining trail, moving from near the treeline into exposed alpine tundra.

Is this trail suitable for beginner joggers?

No, this trail is not recommended for beginner joggers. It is rated as difficult due to its significant elevation gain (over 1,300 meters) and high altitude, with the summit reaching 14,270 feet. The primary challenges are the strenuous cardio demands and the need for acclimatization to avoid altitude sickness. While considered one of the 'easier' 14ers for hiking, it's a 'double black diamond' for trail running in some classifications.

What can I see along the route to Grays Peak?

The trail offers stunning panoramic views of the Rocky Mountains and the Continental Divide. You'll pass by the Grays and Torreys Summer Trailhead and eventually reach the summit of Grays Peak itself. From the summit, you can see neighboring 14ers like Torreys Peak, Mount Kelso, and Mount Edwards. The lower sections feature wildflowers in summer and glimpses of historic mining works. The 'morning glow' illuminating the surrounding mountains is a particularly special sight.

Does the trail intersect other well-known paths?

Yes, the route is part of several other notable trails. It covers 100% of the CDT - Colorado Section and 10% of the Continental Divide National Scenic Trail. You'll also find sections of the Grays Peak Trail, Grays/Torreys Connector Trail, and the Grays Torreys Saddle Trail along the way, offering opportunities to explore further.

What should I pack for jogging the Grays Peak Trail?

Given the high altitude and variable mountain weather, essential items include plenty of water, high-energy snacks, layers of clothing (even in summer), rain gear, sunscreen, sunglasses, a hat, and a first-aid kit. Trekking poles can be very helpful for stability on rocky sections and during descent. Always carry a map and compass or a GPS device, as cell service can be unreliable.

Can I combine Grays Peak with another 14er?

Yes, Grays Peak is famously climbed in conjunction with its neighbor, Torreys Peak. The two peaks are connected by a saddle, making it a popular option for experienced hikers and trail runners to summit both 14ers in a single outing. This adds to the challenge and the reward of incredible views from both summits.

Are there any specific regulations for jogging in Arapaho National Forest?

While there are no specific jogging regulations beyond general trail etiquette, remember that you are in a protected natural area. This means practicing Leave No Trace principles: pack out everything you pack in, stay on designated trails, respect wildlife, and properly dispose of human waste. Campfires are often restricted, especially during dry periods. Always check for current fire restrictions before your visit.
