Here is our BEFORE picture in front of one of the easiest/cleanest obstacles.
Then we got to "bathe" in the river near the finish line.
This last pic is after our "baths". You can see one of the obstacle behind us. You had to climb over this (slippery, muddy) wall using the attached (slippery,muddy) ropes.
(I wish we had some action shots, but there was really no way to take a camera/phone with us. There were a few of us taken by the event photographers, but none that we wanted to buy for $12.)
