New courses this year

We've run the same course for 11 years. Time to change. We will still have the beauty of Dallas in early spring, but we are removing much of the hills and rolling course with the full marathon. We would be delighted to have your participation!

To look at our proposed new courses - (Click Here)

Big D - The name says it all!

On top of running the most beautiful course in DFW, all registrants will receive a unique event tech t-shirt, a finisher medal and enjoy some serious post-race food and libations. Runners will also get their name called out as they cross the finish line. Big D always hosts great entertainment and vendor booths right next to the finish line


Thanks for your interest in volunteering! We have all kinds of volunteer positions that need to be filled. To register as part of our volunteer team please complete a registration by [clicking here]. We will then contact you and work out the details.
