Day Hikes While You Are Here
From Lajitas and Terlingua, there are some great trails you can get to in a few minutes, and hike for an hour or two, or make a day of it.  See our new day hike page.

On Monday after the race, a guided hike by Ranger Amber Harrison will leave at 10 am from the Contrabando Trailhead for a 6 mile round trip hike. An easy hike to loosen up after the races, it will be on the Fresno Divide Trail. We need a minimum number of participants, so sign up in advance.   See our new day hike page.

A Great Event !!!

The Big Bend Ranch State Park is a fantastic place to run, and the Big Bend 50 owes it all to the volunteers, park rangers, EMS teams, ham radio operators, hotels, campgrounds, timing team, sponsors, and our great runners for making it happen, keeping everyone safe, and having fun.

The 2019 event is again managed by race director Carroll Voss of Overland Race Management, and a motley crew of dedicated volunteers you’ve met at the Big Bend 50 events for the last decade and then some.
