Huntsville Runfest 50K

The climbing is the story here. Huntsville's fall trail weekend sends its 50K field around a mountain loop twice, stacking up more gain than most southeastern ultras of this length. A 25K and a short climb-focused 5K share the morning, and proceeds support childhood cancer research, which gives the day a strong local-community pull beyond the racing.

The 50K runs two laps of the 25K loop through the Two Mountain Trail system above McMullen Cove, with each circuit climbing roughly 2,500 feet on mostly singletrack. The route passes landmarks like Pancake Hollow, Blake's Cabin, and Sublett Point, and the rocky, wooded terrain rewards runners who hike the steep pitches and run the ridgelines rather than forcing an even road-style effort.

Late October in north Alabama usually starts cool, often in the 40s, and warms toward the 60s under the trees. Fresh leaf fall can hide rocks and roots on the singletrack, which is often a bigger factor than temperature. Humidity is usually easing by this point in the season, and heavy heat is unlikely.
