A San Antonio original trail running event!

The Chupacabra is an adventurous nighttime run on wooded, unpaved trails. Fire up your headlamp and watch for the glow sticks and other trail markings as you navigate your way through the unpaved trails of McAllister Park under the stars. With a 9 p.m. start, a headlamp or flashlight is MANDATORY! Your entry includes a cool performance fabric T-shirt and a finisher medal, along with post-race Alamo Beer Co craft brews on tap for those of age.

About this Event

This trail event starts and finishes at Classic Elite Soccer Complex and follows the unpaved trails of McAllister Park.  The course runs through heavily wooded dirt trails in the dark. The 5K and 10K run completely different routes except for the last 1/2 mile where they join together. A flashlight or headlamp is required and extremely necessary. The trails can be very rocky with tree roots in places, as well as low branches so paying attention is critical. There are many opportunities to fall. This is not a trail run for beginners.  Trails are marked with signage and glow sticks in the trees. Glow sticks guide you along the trail but do not illuminate the ground, so make sure you have a good headlamp and/or flashlight. All runners will receive a tech shirt and post race beer (for those of age).  This is a fun run.  No awards will be given but overall results will be posted at the event and online.

10K and 5K Courses

Both 5 & 10k distance starts and finish at Classics Elite Soccer Academy Fields on Starcrest. The 5k will take a hard left at approx .75 mi after the start and run a separate course from the 10K.  The 5k will have 1 water stop on the course and one at the finish.  The 10k will have 2 water stops on the course and one at the finish.
