An Ellicott City man died over the weekend after an accident on the Tough Mudder obstacle course in West Virginia, the first such death in the three-year history of the outdoor run that bills itself as “Probably the Toughest Event on the Planet.”

Avishek Sengupta, 28, was with a half-dozen friends on the course Saturday when he jumped from a plank into a deep pool of muddy water, a friend, Dan Gemp, said. Sengupta did not resurface and was pulled out after several minutes by a diver on site, Gemp said.

Sengupta was taken off life support at a Falls Church hospital on Sunday, Gemp said.

Tough Mudder released a statement Monday acknowledging that a 28-year-old man died after running the course.

“At Tough Mudder, safety is our top priority,” the company said. “We thoroughly inspect and test all obstacles . . . and have fully trained medical staff on-site.”

The local sheriff’s office is investigating Sengupta’s death, Tough Mudder said.

Gemp said Sengupta’s family and friends are devastated.

“You know that one guy in high school who was friends with everyone, who got all the hugs?” Gemp said. “That was him.”
