Half Marathon, 5-miler and Kids Mile

Virtual Options Available

In 1979, the Austin Runners Club organized a race on the roads around Decker Lake in east Austin. The Decker Challenge was born! 


Today, the Decker Challenge Half Marathon is one of the longest running races in Austin. December 10, 2023 will be our 45th annual event! All finishers receive a race t-shirt, free post-race photos, finish line festival, and a highly-coveted Decker Challenge finisher’s medal. 

We will also host our Decker Challenge Kids Mile in conjunction with the race festivities. Kids will embark on a moderately challenging 1 mile course, and will celebrate their accomplishment at the same finish line as the half marathon!

Additional Event Information

If you are not able to join us for the in-person races, we are offering a virtual option for the Decker Challenge half marathon. Virtual options will include the official race shirt (shipping costs included), along with any sponsor promotions or special offers from our partners. 

If you are part of the 2023-2024 Distance Challenge and plan to run the Decker Challenge as a virtual race YOU WILL NEED TO REGISTER FOR THE VIRTUAL OPTION through your DC Event Dog registration portal.
