Michael Phelps once opened up about a heartbreaking moment when he lost an important member of the North Baltimore Aquatic Club. He began swimming at the age of seven and joined the NBAC when he was 10, to train under his longtime coach Bob Bowman.
The late Jim Lears was NBAC's treasurer and handled the finances for Phelps and Bowman. The swimmer trained at the North Baltimore Aquatic Club until his appearance at the 2004 Olympics in Athens. In his candid memoir 'Michael Phelps: Beneath the Surface,' originally published in 2004, the former swimmer reflected on the challenging moment when Mr. Jim passed away of a heart attack at 55.
Remembering the day, Phelps expressed how upset he was, but tried to train anyway. He further added that Bowman noticed him being off during the training and ended the session early to sit and reflect on the sweet memories of Mr. Jim.
"We went to a viewing for Mr. Jimmy down the street from my home, and I couldn’t bring myself to stay very long. There were pictures of him throughout the funeral home. I walked up to his casket for five seconds and then went outside with Hilary and lost it in the parking lot. I walked home and cried myself to sleep."
