Autumn Harvest Trail Weekend is a two-day trail running series at Lake Bastrop in the Lost Pines area of Central Texas, held in the fall. The weekend offers a range of events from short trail races to long endurance efforts, with options including a 5K, 5-miler, 10K, 10-miler, 20-miler, half marathon, marathon, 50K, and a Last Standing ultra. Saturday is the Ultra & Distance Day, featuring the longest events designed for runners seeking hours on dirt trails.
The courses traverse fast dirt trails alongside Lake Bastrop, featuring winding lakeside sections, open skies, and tall pines. The most unique event is the Last Standing ultra: participants begin at Basecamp on the Gideon Loop and complete a 4.17-mile loop each hour. This format can extend to 24 loops, approximately 100 miles, with a 50-runner limit and a cumulative-time tiebreaker if necessary. The 9:00 AM start time means runners will face the heat of the day, sunset around the tenth hour, a full night, and potentially into the next morning if they meet the hourly cutoff.
