The Powerline climb is an infamous uphill during the later stages of the Leadville 100 mile run. This steep dirt road is a common training ground for those getting ready to race at 10,000 feet. The road tops out at Sugarloaf Pass (roughly 11,200 feet) where the road and Colorado Trail intersect.

This portion of the trail is relatively flat, nontechnical singletrack along the eastern slope of Mount Massive with fantastic views of the valley through the trees. There are plenty of little streams to refill water.

The hatchery is a cool spot to stop in the middle of a road run. There aren't a lot of flat routes in Leadville, but some of the nearby valley roads can be utilized for flat, paved runs. Owned and operated by the Forest Service and U.S. Fish and Wildlife Service, the Leadville National Fish Hatchery is an educational, recreational, and developmental space serving as a gateway to the Mount Massive Wilderness in Leadville, Colorado. There are informational signs around the hatchery and its trails, and you can even observe and feed the trout they house. There are restrooms and plenty of parking all around the hatchery premises.

Highline Trail is a 10.1 mile point-to-point trail starting at the Leadville Fish Hatchery and popping out near the Windsor Lake Trailhead back in the Mount Massive Wilderness. You can connect this trail to a bunch of others to created different loops.

True to its name, Swamp Lakes are as much marshy bogs as they are actual lakes. Their water levels depend on the time of year, but the trail is better known for the wildlife that frequent the area rather than the actual lakes. Be prepared for some muddy miles near the top if you decide to run this one.

Once you branch off of the Colorado Trail, the route to Massive becomes steeper. After breaking through the forest at treeline, the trail becomes less steep as is starts to climb through the rocky alpine meadows towards the saddle. There are often seasonal pools of water, wild flowers, and lots of marmots and pikas on this section of the route. The trail is too steep to run in most spots when you are breaking through treeline, but some of the meadows offer the opportunity for uphill running above 12,000 feet. This is an excellent portion of trail for downhill running and is welcomed with open arms after dropping down from the talus and scree higher up.

At 14,428 feet, Mount Massive is the second highest peak in Colorado. It is a popular summit due to having multiple routes and mainly only requiring class 1 and class 2 moves to reach the top. Like all 14ers, the weather can change fast, and it's best to try to get below treeline as early in the day as possible during the spring and summer months. The ridge and summit involve some fun rock hopping, but the lower trails offer great running through meadow and basin trails.
