The Experience

The Mosaic Trail Race turns a December Saturday into a celebration of community on the banks of the San Gabriel River, just outside Austin. The course loops through a historic Texas ranch in Liberty Hill, winding along dirt trails that offer a gently rolling terrain—perfect for trail newcomers. With a median field of about 65 runners, the event feels intimate and welcoming, drawing a mix of local families and runners from the wider Austin area. Nearly one in five participants returns year after year, a testament to the race's warm, low-key vibe.

The half-marathon is part of a larger weekend of distances from 1 mile to 50K, all sharing the same scenic ranch trails. Finishers receive a shirt (order by early November to guarantee yours). The weather in early December is usually mild, with average temperatures in the 50s and low humidity. While the course is modest in scale, its emphasis on togetherness and play—'a mosaic of fun'—makes it a standout for those seeking a relaxed, family-friendly trail experience. It's a hidden gem for runners who value connection over competition.

Race-provided description

Saturday, December 5, 2026. Location Canyon of the Eagles, Burnet TX. All of us are like pieces of a mosaic.  We're all different sizes, shapes, colors, styles, ages...But when we join together for a common goal, we create a beautiful picture together, a mosaic of fun if you will! And nothing is more fun than playing in the dirt together! So, we created this trail running weekend in the outskirts of Burnet, at the beautiful Canyon of the Eagles LCRA Park, to give us an excuse to play together.  All ages, ethnicities, backgrounds, and generations are invited to run and hike these trails at an awesome park, just outside the city, on the north shore of Lake Buchanan. This race is truly for everyone, with really generous cutoffs so you can hike for relaxing, or race competitively, or anything between. And we are especially challenging families to make a common goal to exercise together, to finish a race together, to play in the dirt together, to try something new together, and to come together to help complete this massively fun mosaic with others in our community! While every racer will get some cool swag, November 10 is the deadline to get a shirt. Click Here for Tejas Trails Policies (you really do want to know this stuff!)
