Lost Pines Endurance Challenge : Lake Bastrop, Texas
The Lost Pines Endurance Challenge is a two-day trail event held in January over MLK weekend at Lake Bastrop South Shore Park. Races use the North-South Trailway as an out-and-back course that connects the park's South Shore and North Shore areas.
The trail surface mixes packed dirt, sand, rock, and pine needles with rolling elevation changes, bridges, and creek crossings. Scenery includes loblolly pines and lake views. The course is well marked and maintained. Headlamps are required after dark. Full aid station support is provided on Saturday.
The weekend program separates events across two days, with Saturday featuring a 5K, half marathon, marathon, an 8-hour timed endurance event, and ruck divisions for select distances. Sunday features 10K, 10-mile, and ruck options plus an awards ceremony and a post-race gathering. Lake Bastrop South Shore Park offers cabins, RV hookups, and tent camping; Bastrop downtown is nearby for post-event amenities.
