Exploring the Javelina Jundred Course

The course of the Javelina Jundred stands out for its demanding yet breathtaking layout, employing a 5-loop format that challenges runners both physically and mentally. Each loop takes runners through a scenic yet tough terrain of the Sonoran Desert, with expansive vistas, rocky sections, and sandy stretches that demand strategic pacing and resilience. The multi-loop format allows runners to revisit aid stations multiple times, facilitating better hydration management and mental segmentation of the race into manageable portions.

This setup not only promotes strategic planning but also fosters a vibrant community atmosphere as runners cross paths repeatedly. The desert environment presents unique challenges: high daytime temperatures, dry air, and exposed trail sections that underscore the importance of hydration and preparation. Whether tackling the 100-mile race, the 100K, or the 31K shorter event, understanding the course’s terrain and features is essential for successful completion.

Trail Distances

• First Loop: 22.3 miles
• Loops 2-5: 19.45 miles each

Course Overview

The race commences and concludes at the Javelina Headquarters located within McDowell Mountain Regional Park. The loop includes segments across trails like Shallmo, Pemberton, and Cinch, with the initial loop incorporating a section of the Escondido Trail. The terrain is a blend of rolling single-track paths, rocky climbs, dry washes, and striking desert flora, creating a challenging yet scenic route.

Support and Aid Stations

Support stations are pivotal to a successful race experience, offering vital hydration, nutrition, and morale boosts.

The longest distances between aid stations are approximately 6.5 miles from Coyote Camp to Jackass Junction and 6.6 miles from Rattlesnake Ranch to the race start/finish at Javelina Headquarters.

Runners are advised to carry at least two bottles of water, with additional hydration gear recommended for those aiming for a 24-30 hour finish. Given the desert’s heat, carrying extra water and electrolytes is crucial, especially during peak daytime hours (8:00 AM to 5:00 PM).
