Lost Pines Endurance Fest 5K to 250K
The Lost Pines Endurance Fest is a multi-distance trail event held January 16–18, 2027 at Lake Bastrop North Shore and South Shore Parks in Bastrop, Texas. The event uses the North-South Trailway as an out-and-back course with packed-dirt singletrack, sand, rock, pine-needle stretches, wooden bridges, creek crossings, and lake views. Trails have rolling terrain, are well marked, and have full aid station support during race days. Headlamps are required for running after dark. Typical January temperatures are given as mornings in the 40s to 50s°F and afternoons in the 50s to 60s°F.
