Similar to fighting in the trenches in war, this military style obstacle is not set up for the weak minded. Claustrophobic people, this is set up to trap you. Drop into a mud pit and squeeze into a hole two feet wide. Inside the nearly pitch black tunnel, crawl 30 feet through mud, hook a sharp left for ten feet, a sharp right for ten feet, and you’ll see the light at the end of the tunnel. Literally.
Hint: Crawl through the tunnel in a human chain because it’s much easier to navigate in a group. Stick together to calm nervous claustrophobic teammates.
