The Electric Eel obstacle was the first one encountered with the live wires, and this was well before the the famed Electroshock Therapy at the finish line. It is a crawl through frigid and or muddy water, through a low hanging frame of live wires.
Admittedly, it is a little intimidating to dive right in, not knowing what to expect when you get shocked. Talking to other Tough Mudders prior to the obstacle, a couple people described it as getting punched hard really quick. I disagree that assessment, it feels like you are getting effin shocked, and it sucks.
The strategy I found to be helpful was to stay low, and go fast. Keeping as low as possible, I was able to sneak underneath a significant portion of the wires, and I tried to go fast as I could, in hopes to mitigate getting stuck in one place. I managed to navigate about 3/4 of the way through, before I took a shock to the back of the ear. If you can avoid it, try not to take one to the face, it hurts, but that also picked up my pace and I got the out of there quickly.
When it is all said and done, it doesn’t feel good, but nothing you can’t handle. Stay low and go fast, you will most likely get at least one or two shocks, and it will just make you angry. The sooner you burn through the obstacle, the sooner you can turn around and watch your poor teammates faces as they take their first shock, and see that look of anguish on their faces, because if I didn’t mention it, it kind of hurts, but really funny when you see your good friends getting pissed off as they get shocked.
