Mariposa county's classic Merced River Canyon Race returns this year with two options for runners.

McCabe Flat Flat out. This 5 mile race is from the Briceburg bridge to McCabe Flat campground and back (2.5 each way). As the name suggests this race is about as flat as a race in the foothills can be. This race can be done at any pace but some will choose to try and set a record on the flattest footrace in the county.

Burma Grade. This 9 mile race starts at the river level and climbs up the mighty Burma Grade (4.5 each way). This race offers the most elevation of any foot race in the county and leaves the racers with an amazing sense of accomplishment.

Both races are on hardpacked unpaved roads and offer amazing scenery in the Merced River Canyon.

Note on location and directions, please take highway 140 to get to Briceburg. While there are other ways to get here, they are not recommend, especially not on race day.

    Paseo de Mariposa Trail Race

    April 19, 2026 – Mariposa, California

    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.

    About the Event

    Nestled in the Sierra Nevada foothills, just outside Yosemite National Park, Mariposa is rich in history and natural beauty — the perfect setting for outdoor adventure. On Sunday, April 19, 2026, join us for the seventh annual Paseo de Mariposa Trail Run, featuring 5K and 12K courses that begin at the historic Mariposa Courthouse (built in 1851, the oldest courthouse west of the Rockies still in use).

    This family-friendly community event celebrates health, wellness, and active lifestyles. In support of our mission to engage youth in outdoor activity, all children under 18 can participate in any race for free.

    Race Distances

    5K – Family-Friendly & Beginner-Friendly

    Shortest and most accessible option.

    Starts at the courthouse, with sections on paved roads, a short climb past the high school, and a dirt fire road turnaround.

    Perfect for families, walkers, and those new to trail running.

    12K – The Big Adventure

    Longest and most challenging route.

    Features steep descents, a creek crossing, and a tough single-track climb to Slaughterhouse Road and the Flume Trail.

    Stunning views along rugged single-track with significant elevation gain.

    No strollers permitted; youth under 13 must be accompanied by an adult.

    Safety & Support

    Aid stations will be positioned across all distances.

    Trails include technical terrain — rocks, roots, and climbs — so please run or hike your route ahead of time if possible. Bringing a buddy is always recommended.

    For everyone’s safety: no dogs are permitted on any route.

    Why Join?

    The Paseo de Mariposa is more than a race — it’s a celebration of community, family, and the outdoors. Whether you’re chasing a personal best, enjoying a scenic hike with friends, or introducing your kids to trail running, this event is designed for all ages and abilities.

    ✨ Mark your calendars for April 19, 2026!

    On January 28, 2013, Luc, a United States Air Force pilot was on a training mission over the Adriatic Sea off the coast of Italy. During the sortie, Luc was forced to eject from his F-16 and did not survive the ejection. Luc is survived by family and friends who continue his Legacy through the Major Lucas Gruenther Legacy Foundation.

    Major Lucas Gruenther was an incredible human being. He was an outstanding F-16 fighter pilot, community role model, and a true humanitarian. He lived his life to the fullest and never took a single day for granted. Luc is remembered for the way he treated people with wisdom and kindness and was a genuine human being who made a tremendous positive impact.

    All proceeds from this race go to the Major Lucas Gruenther Legacy Foundation, an IRS-approved 501(c)(3) non-profit organization. The purpose of the Major Lucas Gruenther Legacy Foundation is to bestow scholarships to Americans for the advancement of educational goals and self development.
