Running the Austin Marathon comes with a post-race perk.

On Feb. 17, both locations of Fresa's will offer Austin Marathon runners one free taco of their choice when they present their race medal.

Fresa's offers four kinds of lunch and dinner tacos, including the La Fresa, made with pulled achiote chicken, guacamole, grilled onion and cotija cheese.

The location on Ninth Street and North Lamar offers walk-up and drive-thru service only. Fresa's South First location has an extended menu and full sit-down service.
