Welcome!

Welcome to the 3M Half Marathon!

This year join over 7,000 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 that takes you past some of Austin’s finest locations and finishes 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!

Check out our website for everything from course maps to spectator information. Having trouble finding what you are looking something? Simply click the “Live Chat” button in the bottom right-hand corner of the screen, and our staff will be happy to help.

We look forward to seeing you at Downhill to Downtown on 01.21.2018!

The 3M Half is a fantastic event. The shirts and swag are awesome, the medals are impressive, and the post-event venue can’t be beat.
