LeClair worked for Athenahealth in Watertown.

“He was loved by all, known to be incredibly social. He loved the outdoors and was a friend beyond just a co-worker,” Holly Spring, director of communications, said.

Race organizers decided to continue with the event.

“All of us at the American Lung Association express our profound sadness at this tragic loss of life and offer our deepest condolences to the family,” said Jeff Seyler, president and CEO of the American Lung Association of the Northeast. “With heavy hearts, the Trek is continuing.”
