At just over 5k—my official time and pace: 42:43.30; 11:33/M; #894 overall for men, equaled 3.75 miles—the course was closer to what I imagine a good trail run is like, with a lot of hills, mud and water, and a bunch of moderately challenging obstacles peppered throughout.

Hands down, Tough Mudder is the most physically and mentally challenging thing I've ever done, and I loved every minute of it! The temperature was still below 40 degrees when we started just past 9:40am, but the adrenaline was flowing and for the first half of the 12-mile course, it was surprisingly smooth sailing.
