Austin Rattler Run 2026

The Austin Rattler Run is an off-road trail running race held at Reveille Peak Ranch in Burnet, Texas, about an hour northwest of Austin. It is produced by Life Time as part of the Leadville Race Series qualifier circuit, and the 50K is an official qualifier for the Life Time Leadville Trail 100 Run in Colorado. The 2026 edition runs Sunday, November 15, the day after the Austin Rattler MTB races.

The course is a loop of Texas Hill Country singletrack and fire road, offered at three distances: 10 miles, 20 miles, and 50K. Entry is $120 for the 10-mile, $135 for the 20-mile, and $150 for the 50K; runners under 18 take $30 off any distance. Minimum age on race day is 12 for the 10-mile, 14 for the 20-mile, and 16 for the 50K.

Race morning: parking opens at 5:00 a.m. and packet pickup runs 5:30-7:15 a.m. The 50K starts at 7:15 a.m., the 20-mile at 7:20 a.m., and the 10-mile at 7:25 a.m. Runners must begin their final lap by 1:00 p.m. and finish by the 4:00 p.m. official cutoff; finishing inside that cutoff is required for the 50K to count as a Leadville qualifier. Awards are at 12:00 p.m. for the 10- and 20-mile and 3:45 p.m. for the 50K.

The single aid station sits at the start/finish, so runners pass it every 10 miles: no aid station access on the 10-mile, one pass on the 20-mile, two passes on the 50K. It is stocked with GU Energy Roctane hydration, GU gels and stroopwafels, Bobo’s bars, and pickle juice.

Leadville qualifier coins go to 50K finishers only. A minimum of 35 coins are awarded at this event, distributed by a combination of overall and age-group placing plus a lottery draw held at the 3:45 p.m. 50K awards ceremony, and you must be present to receive one.

The Rattler runs as a weekend rather than a single race: a free Little Rattlers kids race is held Friday, November 13 at 4:00 p.m., the MTB races run Saturday, and the run races Sunday. On-site camping, live music, and barbecue are part of the event. All distances register through a single Let’s Do This portal, linked from the race page on austinrattler.com.

Course maps, packet pickup details, and the full weekend schedule are published on austinrattler.com; the Austin Rattler is run by Life Time’s own event staff, so registration, transfer, and refund questions go to them directly.
