The event is not officially timed, but typically takes three to four hours to complete.

In that time, participants — either individually or in teams — submit themselves to an array of difficult — and unexpeced —obstacles.

Those include, but are certainly not exclusive to, monkey bars suspended over icy water, a greased quarter-pipe, and dark trenches that need to be crawled through.

What awaits the participants in the Seneca event is unclear because Tough Mudder does not disclose specific obstacles before start time to keep participants ready for anything.

Hamilton said that while many of the obstacles — like, say, the electric wires — are difficult to train for, there are ways you could prepare.

“It’s an endurance event,” he said. “So it’s important to be in shape cardio-wise.”

But, he said, the most important part of the race is that — individual or team — most of the event cannot be done alone.

“A lot of Tough Mudder is about comaraderie and working together,” Hamilton said. “It’s having others there with you that makes it fun.”

That’s something Tough Mudder explicitly promotes, both in the event and outside it.

Participants, for instance, recite a pledge before embarking in which they vow to “put teamwork and comaraderie before my course time” and to “help my fellow mudders complete the course.”

The event also raises money for the Wounded Warrior Project, providing combat stress recovery programs, adapative sports programs, benefits counseling and employment services to veterans.

As of press time, Tough Mudder has raised close to $5.5 million for the Wounded Warrior Project.

It’s a challenging course to make it through, but one Hamilton said is ultimately worth it.

“It’s about the challenge of it,” he said. “I want to challenge myself.

“It will be a lot of fun.”
