I003n a secret location north of San Antonio, there is an annual 5K Mob Run and a very unique one at that. It’s set up in an active rock quarry, meaning that every year’s course can be completely different from the year before. There are some permanent obstacles, but each year the race directors look for new ways to challenge the competitors. I was able to ask the race directors, Laura and Kevin Tift, some questions about ThunderDash.
