Running

Embark on the Mount Jefferson Loop via Caps Ridge Trail, a difficult jogging route spanning 4.9 miles (7.9 km) with a significant 2591 feet (790 metres) of elevation gain. This challenging path, estimated to take 1 hours and 55 minutes, leads you through rugged terrain that often requires careful foot placement and using your hands to navigate steep, rocky sections. As you ascend, you'll break above the treeline for about half of the journey, revealing expansive panoramic views. The trail is known for its three distinct "Caps" or rocky knobs, which provide unique scrambling opportunities and continuous vistas of the surrounding White Mountains. From the summit of Mount Jefferson, you can spot Mount Washington and other Presidential Peaks.

To begin your jogging adventure, you'll access the highest-elevation trailhead on a public road within the White Mountains, which allows for quicker access to higher altitudes. Be prepared for rapidly changing weather conditions, especially in the exposed sections above the treeline; always check the forecast before you go. This route is best enjoyed when conditions are clear and stable, given its demanding nature and high-altitude exposure. Plan to start early to allow ample time to complete the loop safely.

This particular route stands out for its unique geological features, specifically the three "Caps" that define the Caps Ridge Trail. These rocky formations offer not only a physical challenge but also continuous, unobstructed views that are a hallmark of the Presidential Range. The trail's ascent to Mount Jefferson, the third-highest peak in New Hampshire, provides a sense of accomplishment and a vantage point to appreciate the vastness of the White Mountain National Forest.
