THOR stands for Texoma’s Hellacious Obstacle Run. It is possible that THOR is the one thing you’ve been missing out on your entire life. Simply put, THOR is a 5(ish)K trail run full of obstacles and adventure. You’ll be expected to run, wade, climb, traipse, hustle, dash, duck, dodge, and jump throughout the adventurous course designed to be fun, but competitive. You will get dirty. And you will like it. Actually, you will most likely end up loving it.
