Outlast Houston

Outlast Houston is a trail endurance event held February 20-21, 2027 in Navasota, TX (18135 FM-362). The format is multiple hourly 5K laps: participants run a 5K each hour and must finish each lap within the hour to continue. Missing a lap removes a participant from further rounds. If a participant finishes early, they rest until the next hour.

Distances offered:

  • 6 hour : six 5K laps (18 miles)
  • 12 hour : twelve 5K laps (36 miles)
  • 24 hour : twenty four 5K laps (72 miles)

Courses are trail based with natural terrain, elevation, and occasional pavement or gravel. Each 5K is timed individually; a participant who completes all laps has a combined time that counts toward local results and the national leaderboard. Aid is available at the basecamp or loop start with water, basic hydration, and snacks; the event is cupless so participants must bring their own bottle or hydration system. Participants may walk as long as they finish each 5K within the hour. Tent or personal aid station setups are permitted at the site.

Awards and recognition include patches for intermediate lap totals, premium medals for 6 and 12 hour finishes, a buckle for 24 hours, a premium event tee for all participants, local division awards, and national ranking with prize money for top performers.
