The Ultra & Distance Day

Autumn Harvest Last Standing

Start: 9:00 AM  |  Cutoff: 24 hours   |  Distance: 4.17-mile loop, up to 24 loops (~100 miles) Format: Last Person Standing with cumulative time tiebreaker. Field Cap: 50 runners. One loop. One hour. Last runner standing wins. 24 hours at Lake Bastrop. Are you in?

The 9:00 AM start means you'll run through one full day, one full night, and into a second morning. Sunset falls around 7:15 PM, approximately 10 hours and 2 loops into the race. Runners must have mandatory night gear ready before the 7:00 PM loop.

If you're the last runner standing, you'll complete a victory lap to claim the win. If multiple runners survive to 9:00 AM Sunday, the lowest cumulative time wins, and yes, they still have to complete a victory lap.
