Get active and get a sneak peek at Austin's favorite holiday celebration at the annual Austin Trail of Lights Fun Run.

The two mile run will start at the historic Zilker Tree and end within the Trail of Lights. This is a unique opportunity to see the Trail of Lights before it opens to the general public. The Zilker Park route is family-friendly, all speeds are welcome and kids in strollers ride for free. Costumes are highly encouraged, so grab your Santa hat and your sneakers. There's still time to register, but if you don't want to participate, you're more than welcome to spectate or volunteer.
