Now in its 15th year, the Austin Trail of Lights Fun Run pairs festive fun with philanthropy, welcoming participants of all paces for an untimed, 2-mile course that steps off at the iconic Zilker Holiday Tree and winds through the illuminated Austin Trail of Lights in Zilker Park. New this year is a rolling-start experience, giving guests flexibility to begin any time between 6 and 8 PM. Registration includes a commemorative long-sleeve Fun Run T-shirt, a 2026 Race Bib, complimentary cocoa or beer for guests 21 and up, Finish Line Festival admission, and free photos with Santa and Mrs. Claus.
