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!
So, we created this trail running weekend right here in the outskirts of Austin (in the rapidly-growing Liberty Hill) 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 historic Texas ranch, right next to the city, on the banks of the San Gabriel River. 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.
