2026 Decker Challenge

Race Information

In 1979, Austin Runners Club organized a race on the roads around Decker Lake in east Austin and the Decker Challenge was born. Get ready and join us on December 10, 2023 for the 45th running of one of Austin’s oldest and most iconic races.

The Decker Challenge is a family-friendly event that includes competitive Half Marathon and 5K distances, plus a fun Kids Mile. Challenge yourself on this legendary course and conquer the famous hills of Decker. Once you cross the finish line, celebrate with your friends, family and fellow runners at the finisher’s party. Half Marathon and 5K finishers receive the famous Decker t-shirt, highly-coveted and hard-earned finisher's medal and free race photos.

In addition to the competitive races, there is a fun Kids Mile as part of the overall race experience. Kids will embark on a moderately challenging 1-mile course and cross the same finish line as the Half Marathon and 5K races. All Kids Mile finishers will receive a commemorative wristband.
