Haunted 5K, 10K, & 13.1M at Deer Park, TX

Haunted 5K, 10K, & 13.1M at Deer Park, TX takes place on October 17, 2026, in Deer Park, Texas. Three road races start together at 8:00 a.m.: the 5K, the 10K and the half marathon (13.1 miles / 21.1 km), with a Halloween theme and costumes encouraged.

By mid-October the Gulf Coast heat has partly eased, making the longer distances more manageable than in September. The half is still a serious undertaking, though: aiming for an even pace rather than an eager start helps avoid fading after the 10K mark. The 10K is a useful checkpoint for anyone building toward a year-end goal race, and the 5K welcomes beginners. Prizes reward both the fastest times and the most original costumes, and every finisher receives a medal.
