Monster Dash begins at Comanche Park in San Antonio, centered around Halloween. Runners, walkers, wheelchair athletes, and virtual participants are welcome. The event features a half marathon, 10K, 5K, a 5K wheelchair division, and a 1-mile run/walk/roll, plus a virtual option. It is hosted by the Now You SEE Me Foundation, with proceeds supporting spinal cord injury research and aid for Texas cyclists and runners who have sustained life-altering injuries during training.
The longer races and the 5K wheelchair division provide water stops and Gatorade. Overall, masters, and age-group awards are given for multiple distances. The day includes a costume contest for participants, and pets can also compete in the costume contest for an additional fee. All finishers get an event shirt, medal, a Chick-fil-A meal card, Las Palapas breakfast tacos, and post-race drinks from Heineken and Dos Equis.
