Monster Dash 5K, 10K, and 1 Mile

Monster Dash 5K, 10K, and 1 Mile takes place in Weslaco, Texas, on October 31, 2026. The 10K, 6.2 miles, and the 5K, 3.1 miles, both start at 8:00 a.m., and the one-mile Little Monsters Dash follows at 9:15 a.m.

Having a 10K and a 5K on the same morning makes this an easy race to come back to year after year: run the shorter one while you are building, then move up once your weekly mileage supports it. For the 10K, the key session is a tempo run of 20 to 30 minutes at a pace you could sustain for an hour, once a week, alongside a long run. For the 5K, swap that tempo for shorter, faster repetitions. The mile an hour later gives children a start of their own rather than sending them out among the adults.
