A Note from the Race Director
Hello everyone! My name is Nate Moore, and I’m excited to share that I’ll be directing the 2026 Paseo de Mariposa Trail Race through my company, San Joaquin Running Co.
We love supporting local community events, especially those that celebrate trail running and the unique beauty of our region. Our goal is to carry forward the traditions that make this race special, while adding the same energy and care we bring to our other events.
Through San Joaquin Running, I help organize a variety of races across the Central Valley and Sierra foothills, including the Shadow of the Giants 50K, Pincushion Hill Climb, McKenzie Preserve Half Marathon, Sycamore Island 5K/10K, and others. Each event is built on the same foundation: creating tough, fun, and memorable experiences for runners of all ages and abilities.
I’m truly honored to help guide the Paseo de Mariposa into its next chapter. Together, we’ll keep this race a family-friendly tradition that highlights the heart of Mariposa and the adventure of trail running.
