The Mount Clef Triathlon in Agoura Hills, California, is more than a race—it's a dynamic engagement with the rugged terrain of the Santa Monica Mountains. This triathlon blends trail running, mountain biking, and cross-country running across a challenging but rewarding course that forces you to respect every incline and twist. The route covers approximately 12 miles total, with about 1,200 feet of elevation gain spread unevenly across the segments. Forested paths lined with chaparral bushes and mature oaks guide you through an environment that feels alive, as if the trails themselves dare you onward with every step.

Starting with a mountain bike segment, riders launch into dirt trails riddled with rocks and occasional dry creek crossings. The earth listens but pushes back, reminding you that gear choice and technique matter—knobby tires with strong grip and a steady cadence are your allies here. Next comes the trail run portion, weaving through shaded forest and open ridges where panoramic views of the Simi Hills tease at the edges of your effort. The final run is tougher, marked by steep and uneven terrain that tests your endurance and focus.

Prepare meticulously. Hydration is critical: the southern California heat can intensify quickly, especially from late spring through early fall. Carry a hydration pack or bottles equipped to endure bumps and jolts. Shoes should offer solid traction and support, with breathable uppers to prevent overheating. Timing your effort for early morning reduces sun exposure and offers cooler, less crowded trails.

The environment here holds character; winds from the Pacific occasionally whistle through tree limbs, and the scent of sagebrush fills the air, serving as a fresh but subtle companion to your exertions. You’ll find yourself operating in a push-pull rhythm with this terrain—respecting its toughness without expecting to tame it outright. Each mile delivers variety, from narrow single-track trails to broad dusty fire roads.

For those chasing a hands-on adventure beyond conventional triathlons, Mount Clef offers an off-road alternative that pulls you into the landscape rather than pushing you past it. Whether you come for competition or personal challenge, the Triathlon demands preparation, alertness, and a readiness to engage with something fiercely itself. Embrace the course and it will reward you with views, fresh air, and a genuine sense of accomplishment.
