37th Annual Decker Challenge Half Marathon

Come join us on Sunday, December 6 for the 2015 running of this classic Austin race around beautiful Decker Lake in east Austin. Each registrant receives a technical race shirt and each finisher receives a highly-coveted Decker Challenge finisher’s medal!

The Decker Challenge is the third race of six races in the Austin Runners Club’s Distance Challenge. Net proceeds from the Distance Challenge will benefit The Trail Foundation.

Call Your Shot!

New for 2015, we are excited to present the Call Your Shot competition! In the days leading up to the race, we will email a link where you can predict your finish time at Decker. The two male and female finishers that come closest to their called shot will win a free pair of shoes! Winners will be announced in the days following the race and shoes will be available for pickup at Rogue Running. In the case of a tie, the finisher that runs the most even pace for the whole race will be the winner.

The Course

We are a USATF-certified half marathon course with mile markers at every mile. We will have six water and sports drink stops along the course, approximately every two miles. See course and elevation maps. The course will stay open for four hours.


Runners are permitted to run with music. To ensure the safety of yourself and other runners, please be aware of your surroundings.

Running with a stroller is discouraged. Participation by runners under the age of 16 is discouraged, though exceptions can be made. Please notify vicepresident@austinrunners.org for exceptions.

If you plan on racing in a wheelchair, please read our wheelchair policy and contact vicepresident@austinrunners.org so we can assure your safe participation.

Packet pickup

Packet pickup will be on Friday, December 4 and Saturday, December 5 at Rogue Running (410 Pressler St). There will be race day packet pickup at the Travis County Expo Center, but we highly encourage you to get your race packet early!


Decker is a chip-timed race. Each finisher will see two times in their results–clock time and chip time. Clock time is the time between when the race officially starts and when you cross the finish line. Chip time is the time between when you cross the starting line and when you cross the finish line. Since many runners don’t cross the starting line until a short while after the official start, your chip time is a better measure of the time you took to complete the course.

The race winner will be determined by clock time. All other placements, such as age group winners, will be determined by chip time.


We will be presenting awards to top 3 male and female finishers in the following categories: Overall, Masters, and Age Group (19 and under, 20-24, 25-29, 30-34, 35-39, 40-44, 45-49, 50-54, 55-59, 60-64, 65-69, 70+). Make sure to stick around for the awards ceremony to receive your award! Awards will not be mailed to finishers.


There will be plenty of parking on the Expo Center grounds close to both the Start/Finish and the Banquet Hall. Enter the grounds through the main entrance off Decker Lane and follow parking volunteers’ directions.
