Big Bend Ranch State Park

Register in Advance
We don’t have a cap on the runner count (yet) but we do have to plan our aid stations, and extra runners means extra resources that have to be brought in from far away, or cooked, or screen printed … and deployed in the the days before the run by our volunteers. Dozens of water jugs, electrolyte, snacks, … Registering in advance is the best way.

Packet Pickup – Saturday
During the day, packets will be available at Barton Warnock Center from 10 am to 4:30 and at the start on Sunday morning (at least 30 minutes in advance), but make sure to double check start times, and if you are paying morning of, please bring a check or exact change.

Start & Finish
All share the start and finish at the Barton Warnock Visitor Center at Big Bend Ranch State Park a mile from Lajitas. Plenty of parking, but not right at the visitor center. Very close by. See the map below.

You can drive and park within 100yds of the start/finish. Do not try and park at the race start area. Way too much going on, and there isn’t much space.
