El Chupacabra de San Antonio 5K, 10K

The 2020 San Antonio Chupacabra Nighttime Trail 5k & 10k event is now VIRTUAL ONLY. Our permission to run in person was rescinded by per the City of San Antonio.


Get ready for the Chupacabra! We are holding this event as planned on Oct. 9, with safety precautions and health protocols in place as required by the city officials and the race venue.

One of the safety measures is that we are limited to 250 runners. So if you plan on running, sign up now to be sure you get in.

Also note that the race start time is earlier than in the summer. The 10k starts at 8 p.m., the 5k starts at 8:15 p.m.


When we were forced to cancel back in July, we gave all registered runners the option of running on Oct. 9, deferring their entry to 2021 or transferring their registration to another Run In Texas event.

If you were pre-registered for the original July date for the event, you’re automatically registered for the Oct. 9 event unless we have heard otherwise from you.

About this Event

This is a San Antonio original trail event.  Start and finish at Classic Elite Soccer Complex and run on the trails of McAllister Park.   The actual start is on top of the dam south of the police station for those who know the trails.  It is about 1/4 mile from packet pickup and the finish at the Classic Elite soccer fields.  The finish is inside of the soccer complex.  The 10K will start at 8PM and the 5K will start at 9.   The course runs through heavily wooded dirt trails in the pitch dark.  The 5K and 10K run completely different routs except for the last 1/2 mile where they joing 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. It is up to you to provide your own lighting so you do not take a spill or run into a branch. Trails are marked with signage and glow sticks in the trees. Glow sticks guide you along the trail but do not by any stretch 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.
