BJ’s Wholesale Club chief executive Lee Delaney reportedly died of a heart attack while he was in the middle of a run last Thursday.
One of the reasons Delaney, 49, had taken up running was because of his family's history of heart problems, a family member told Patch.
The retailer said Delaney's death was unexpected and likely due to "natural causes."
Representatives for BJ's did not respond to FOX Business' request for comment.
BJ's executive vice president and chief financial officer, Bob Eddy, has been named interim CEO, effective immediately.
"We are shocked and profoundly saddened by the passing of Lee Delaney," board chairman Christopher Baldwin said. "Lee was a brilliant and humble leader who cared deeply for his colleagues, his family and his community."
Delaney joined BJ’s as executive vice president and chief growth officer in 2016 before being promoted to president in 2019. Prior to that, he was a partner at Bain & Company for 10 years.
Eddy joined the company in 2007 and assumed the role of executive vice president and CFO in 2011.
BJ's operates 221 membership clubs and 151 gas stations nationwide.
