Sunrise Marathon 5K/10K/13.1 AUSTIN/ROUNDROCK

Sunrise Marathon 5K/10K/13.1 AUSTIN/ROUNDROCK is the Austin and Round Rock edition of the Sunrise Marathon series, held on December 12, 2026. The half marathon (13.1 miles), the 10K, the 5K and a one-mile family fun run all set off at 7:30 a.m. for a sunrise start on a scenic course. Timing is available as an option, and entrants get a performance race shirt, a finisher medal and a digital training pack.

Choose your distance by the number of weeks you have actually trained, not by ambition. Ten to twelve solid weeks with one long run each week supports a 13.1; six or seven weeks of running three or four times a week points to the 10K; anything less and the 5K is the one that will leave you glad you entered. All three are run on pavement, so a road shoe you have already broken in is the right call, and a 7:30 a.m. gun means eating breakfast earlier than you think.
