Desert Classic and National Trail Loop

The loop can be accessed from various points within South Mountain Preserve. A common starting point is the Pima Canyon Trailhead, which offers parking facilities. Given the trail's popularity, especially on weekends, arriving early is recommended to secure a spot.

This loop is rated as difficult for jogging. It combines the easier, rolling terrain of the Desert Classic Trail with the significantly more strenuous and technical sections of the National Trail, which features rocky steps, loose climbs, and steep descents. It requires a good level of fitness and careful footing, so it might not be ideal for beginner joggers.

The terrain is quite varied. The Desert Classic Trail portion features a rough-and-rocky tread with numerous wash crossings and mild elevation changes, often described as 'fast rolling terrain.' In contrast, the National Trail is much more technical, following the South Mountain ridge with many rocky steps, ledges, and sections full of loose rocks and steep climbs. You'll encounter both forgiving singletrack and challenging, unstable surfaces.

You'll experience the rugged beauty of the Sonoran Desert. The Desert Classic Trail offers expansive views of the lower desert landscape, with potential wildflower displays during bloom season. The National Trail, being higher up, provides sweeping vistas of the 15-mile long South Mountain range and distant views of the Phoenix metropolitan area. Expect classic desert flora and fauna throughout.

The best time to jog this loop is typically between October and May. This avoids the intense summer heat, which can reach 95 degrees Fahrenheit even in early October. During these cooler months, the conditions are much more favorable for a challenging jog in the desert.

Given the desert environment and the trail's length and difficulty, it's crucial to bring ample water – more than you think you'll need. Sun protection like a hat, sunglasses, and sunscreen is essential. Appropriate trail running shoes with good grip are highly recommended due to the rocky and uneven terrain. Snacks, a first-aid kit, and a fully charged phone are also wise additions.

Beyond the physical demands of the difficult terrain, be aware that the trails, especially the Desert Classic, can be very busy with mountain bikers and other users, particularly on weekends. Sharing the trail is common. Always carry plenty of water and protect yourself from the sun, as temperatures can be extreme outside of the cooler months. The technical sections of the National Trail require constant attention to foot placement to avoid falls.
