This is our nighttime party trail run just West of Houston at Stephen F. Austin State Park!

​The trails are wide and mainly gravel/dirt with a few quick elevation changes but a great trail run for beginners to advanced.

​All runners will need both a light and hydration device as mandatory equipment. The trail will be marked with reflectors and ribbons. We are a cupless race so you must carry your own bottle/flask.

Follow park instructions for parking along the right side of the park road, starting at the group dining hall event area and filling back from there.

The group dining hall is where all the action happens; packet pickup, start/finish, spectator hang-out lawn with runners personal area, and our main aid station. A second water refill will be available at halfway at the road crossing.

Extra lights and costumes are encouraged! Sunset is at 7:30 PM.
