I ran the Beast (13.1) and unfortunately there were weather issues. Right after I passed the 10 mile mark, it started to rain. HARD. As in, I could hear it hitting me hard. When I got to mile 11, which had an obstacle (Inverted Wall), the volunteers said they'd been told to shut down the obstacles due to lightning.
Which kind of sucked, because probably 2/3s of the obstacles are in the last couple of miles. I got to finish the course, but it was just running. Okay, doing an old man shuffle/jog.
On to next year!
Note: I did discover a great place for breakfast: the Granbury Pancake House. The term "generous portions" is not generous enough, by a good bit.
