Those who will take part in the Tough Mudder endurance event in Sheboygan  County come from all walks of life. The Appleton Fire Department will be well represented sending a team of 27 participants.  Kris Schuller introduces us to two of those attending, tackling what's being billed "the toughest event on the planet."

As firefighters, Jason Lee and Mitch Lundgaard know the importance of working together when faced with a challenge.  This weekend all the team building skills they've acquired as Appleton firefighters will be put to the test, competing in something called the Tough Mudder.

"Bunch of obstacles, 11-miles,"said Jason Lee. "It's a challenge, something other than just getting on the road and running, bunch of other activities."

For  Lee, it's his first time in the competition.

"Looking forward to the most? Probably the end."

For Lundgaard it's his second crack at the obstacle course, designed by British Special Forces.  But the goal isn't to finish first - instead to challenge yourself and to support your team members along the way.

"It's not a competition," said Lundgaard. " You are not trying to beat the people with you. You instead try to work together to help all of them get through it."

Both men have completed hours of training, designed to help power them across the finish line. But all the sweat is worth it knowing a portion of the proceeds are directed toward the Wounded Warrior Project.  An organization that has been given over $3 million to help  military members who've suffered service related wounds.

"It's a way to lend a hand to our wounded veterans and to let them know they have our support," said Lee.

"Anything we can do to support the veterans is great."

But to complete that goal, they first need to support each other, and their teammates, on the toughest obstacle course on the planet.
