September:

• Zilker Relays: The Zilker Relays is a 10-mile race with teams comprised of 4 runners. Each participant runs a 2.5 mile loop from one central festival/transition area. The combination of a relay, festival home base, drinks and music, make this experience a favorite for runners of all calibers and ages. ​

October:

• The Austin Distance Challenge: Not technically a race, but a series of the five most prestigious local running events starting in the fall and leading up to the Austin Marathon & Half Marathon in February. Participants sign up for the series to compete against personal goals and for awards for Overall, Masters and Age Groups. The five races included in the challenge can be found below.
• Run Free 80s 8K: This 8k encourages you to "accelerate beyond the time barrier with high tops, hot pants, scrunchies, slap bracelets, and the glory of feathered hair!"  The race benefits Run Free Texas, a local cause serving at-risk youth, and is Race 1 of The Austin Distance Challenge.
