Because fast food and running go together like burgers and fries, right?

Shake Shack, a chain restaurant known for its burgers, hot dogs, frozen custard and crinkle cut fries, announced this week the launch of a running chapter at its South Lamar Boulevard location in Austin.

Shake Shack is known for its burgers and crinkle-cut fries.

The “community fitness club,” called Shack, Track and Field, will meet once a month for short, 3- to 5-mile group runs or bike rides. The sessions are free and open to all ages and abilities.

Let’s face it. Most folks won’t show up for the calorie burn. They’ll go in hopes of getting free food.

They’ll get a free soft drink and some unspecified Shake Shack swag. They’ll also get the chance to buy a Shack, Track and Field technical T-shirt for $25. If they wear that to the next run, they’ll get a free cone or cup of custard.

The group will meet the second Tuesday of every month, rain or shine, starting March 8. The group will meet at 7 p.m. at Shake Shack, 1100 South Lamar Boulevard, No. 2100. Runners will head to Lady Bird Lake, where they’ll do the short loop, and then return to the Shack.
