Welcome to the 3M Half Marathon!

Join more than 7,500 fellow runners in Austin, Texas, to run a personal best at the 3M Half Marathon. 3M Half is a fun and fast stand-alone half marathon boasting one of the fastest 13.1-mile courses in the country. You’ll enjoy a point-to-point course with mostly downhill running, run past some of Austin’s finest locations, and finish downtown near the Texas State Capitol. Cross the finish line, grab your hefty one-of-a-kind “spinner” finisher medal, and celebrate at the energetic finish line festival, complete with a beer garden!
