Your New January Tradition Starts Here

• Event: The Lost Pines Endurance Challenge is a brand-new multi-distance trail event set among the towering loblolly pines and shimmering lakeside views of Lake Bastrop.
• Distances: Whether you're chasing your first 5K finish, grinding through a full marathon, testing your limits over 24 hours of running, or loading up the ruck and grinding it out, there’s a place for you at the start line.
• Course: The course follows the scenic North-South Trailway, an out-and-back route that winds through one of Central Texas's most beautiful landscapes, the famous Lost Pines.
• Experience: Expect rolling terrain, packed-dirt singletrack, pine-needle-cushioned stretches, and glimpses of Lake Bastrop through the trees.

We built this race for everyone. First-timer? Welcome. Ultra veteran? Let's go. Rucker with a loaded pack? We’ve got your division. This is a weekend to push your limits, support each other, and celebrate what your body can do.

The Course

North-South Trailway — Out & Back

• Connection: The North-South Trailway connects Lake Bastrop's South Shore and North Shore parks, curving gently through dense pine forest.
• Terrain: Packed dirt, sand, rock, with gentle elevation changes, making it technical enough for real trail running.
• Scenic: Enjoy towering loblolly pines, lake views, creek crossings, and the unique ecosystem of Texas.
• Weather: January mornings in the 40s–50s°F and afternoons in the 50s–60s°F: headlamps are required after dark.

First 5K or Fiftieth Ultra? You Belong Here

The Lost Pines Endurance Challenge was built from the ground up to be the kind of race where everyone feels at home. We want the first-timer to feel the same energy and support as the seasoned ultra runner. We want the rucker grinding under a loaded pack to get the same cheers as the 5K finisher crossing the line with a huge grin.

Timed events (6-hour, 12-hour, 24-hour) are perfect for runners who want to set their own pace and see how far they can go. Run as many out-and-back laps as you can within your time window.

Every mile counts.
