The Ravens team consisted of John and Ingrid Harbaugh, Juan and Zaida Castillo, Kevin and Sally Byrne, Erika Werner, Jennifer LaFluer, Jimmy Ellis and George Vigue.

John Harbaugh crawls through the mud, just under barbed wire during the first of 22 obstacles, the Kiss of Mud.

Harbaugh and Castillo climb off the King of the Mountain obstacle, a huge stack of hay bales.

Harbaugh crawls through the water while being shocked by charged hanging tentacles. The coach was motivating the participant ahead of him to keep moving.

The obstacles are challenging enough, but what shouldn't be forgotten is the freezing-cold runs, many times up hill, that totaled about a half-marathon in distance.

Harbaugh leaps into a trailer full of freezing cold ice water during the Arctic Enema obstacle. He turned to the random participant next to him and said, "We're doing this together, right?"

Harbaugh swims to the end of the trailer full of ice. He was thankful for any sunlight after this.

Castillo takes the leap of faith into the trailer of ice.

Harbaugh and teammates carry a huge log downhill and then back up during the Log Jammin' obstacle.

Participants recognized Harbaugh early during the event and word quickly spread. This fan serenaded the Ravens contingent with "Hail to the Redskins" before gracefully exiting into a mud pool.

Zaida Castillo makes her way over one of the high walls of the second Mud Mile. Participants had to help their teammates to the top of each one.

Harbaugh summits the last mud hill (of this obstacle) before shouting, "I'm king of the hill!"

Harbaugh glad to exit the second Mud Mile.

Harbaugh encourages Ingrid as they go through pipes, then wade through water, and then up through again during the Boa Constrictor.

Harbaugh gave much credit to George Vigue, who was a strong member of the team and went back to the Tough Mudder for another crack at it Sunday.

Ingrid scampers up the Berlin Walls obstacle with the help of Harbaugh and Castillo pushing from the bottom.

Harbaugh climbs over 10-foot walls with the help of his teammates. Much of the event was to encourage team cooperation.

George helps Harbaugh over the Berlin Walls obstacle. This was not easy on the arms.

The thrill of scaling the second Berlin Walls obstacle.

Harbaugh hoists Ingrid onto his back during the Wounded Warriors Carry. At one point, participants are supposed to switch. Unfortunately, Ingrid didn't carry John.

What a man.

Harbaugh and teammates leap over a burning pile of wood into a cold pool of water. And of course they did it in style with a cannonball.

Harbaugh helps random participants up a rope ladder taking them out of the Log Jammin' obstacle.

Harbaugh exits the Cage Crawl obstacle, which was wading through long pools of water upside down hanging from the cage. It was not one of Harbaugh's favorite obstacles.

After swimming through water (just enough to freeze participants), Harbaugh climbs up a high rope ladder with the help of other participants keeping it taut.

Teammates congratulate each other after the difficult Pirate's Booty obstacle.

Ingrid races up the half-pipe obstacle called Greased Lightning. Participants had to build up enough speed and sometimes leapt to try to reach the hands of their teammates, who helped pull them to the top.

A determined Harbaugh builds up speed springing up the half pipe.

Harbaugh is helped to the top of Greased Lightning. Arms have long been tired by this point, so it's a struggle to reach the summit.

With tired arms, Harbaugh makes his way across the Funky Monkey obstacle.

Ingrid, who often times paced the Ravens group, made it the furthest of any of the Ravens participants in Funky Monkey.

The Ravens contingent locks arms to go through the highly-charged Electroshock Therapy. Ingrid said the charge was intense. The team almost stumbled to the mud but kept their feet over the finish line.

Ravens team successfully finished the course.
