Bjorn Borg reveals drug addiction and private battles in new memoir Heartbeats

Bjorn Borg has revealed for the first time that he battled a drug addiction, detailing private turmoil in Heartbeats, his memoir released this week. The 11-time Grand Slam champion writes that a relapse during a 1990s comeback led to a collapse on the way to a tournament in Holland with his father, an episode that opens the book and casts new light on his decision to step away from tennis.\n\nThe sport's quiet icon acknowledges that retirement at the age of 25—followed by years of stardom and wealth—left him feeling lonely and rootless. “Despite the relief of finally having freedom, those feelings of loneliness and rootlessness stuck around,” Borg writes, adding that the loneliness fueled a pattern of self-medicating with drugs, pills and alcohol. He recalls that he had to be dragged out of nightclubs at times in his final event before the break in Geneva in 1981, yet still managed to win the tournament. “Where do I belong? Where’s home, really?” he asks in retrospect.\n\n\n\nBorg's career on the court remains legendary. He held the world No. 1 ranking for 109 consecutive weeks and won 11 major titles, a run that included a famous early retirement in Geneva in 1981 following a period of peak dominance. He says he withdrew not because he lost his drive but because he needed a new challenge and found the isolation of being on top increasingly suffocating. “I had been on top for a long time and needed new challenges,” he writes, reflecting on the decision that would ultimately redefine his life. “Where do I belong? Where’s home, really?”\n\nThe book traces the arc from that decision to the life off court that followed. Borg describes the early-1980s sense that he was losing touch with happiness, noting that “the feeling of isolation just grew inside me, even though I had my family and Mariana nearby.” He adds that he began to self-medicate as a way to cope with dark thoughts and emotional turbulence. He describes the drugs and pills as a dangerous mix that eventually displaced his desire to play tennis and spurred a deeper reckoning with his own mortality.\n\nThe memoir also details a dark chapter in Milan during his marriage to Loredana Berte in 1989 and the years that followed. Borg writes with blunt honesty about a chaotic period marked by personal instability, business failures, and the strain of parenthood. He describes the decision to have his son, Robin, live with him and Berte in Milan, only for the arrangement to become untenable as Robin grew sad and confused. He says the situation was unsustainable and that his family offered support, but the experience left him with lingering shame about putting his son through an unstable living arrangement. The couple would eventually separate, with Robin moving back to Sweden under the care of Borg's then-partner and grandparents.\n\nThe book also documents a hospital episode in 1989 in which Borg was rushed in and had his stomach pumped after a dangerous mix of pills and alcohol. Media attention at the time framed it as a suicide attempt; Borg and Berte say in the book that it was not a conscious end-of-life act, but a moment when the drugs and alcohol overwhelmed him. He describes it as a cry for help and says that the episode changed his perspective on his life and his addiction, intensifying his desire to break free from the pattern.\n\nA further revealing section recounts Borg's secret recovery in London. He says he checked into a luxury hotel in the city and coded a personal rehab program around daily training at the Queen's Club, cutting off contact with old friends who could pull him back into the drug scene. “I left, packing only what I really needed: rackets, shoes, and clothes,” he writes, describing the determined but solitary road to recovery. He credits the London support network there for helping him rebuild his routine while staying out of the public eye, even as tabloids loomed in the background.\n\nThe narrative then returns to the relapse that opens Heartbeats. Borg recounts the European tournament that marked his return to risk. He describes how dinners and wine spiraled into old habits and led to a moment when his body could no longer cope. “Beep. Beep. I woke up in a hospital room, tubes attached to my body,” he writes, recalling the moment his father stood at his bedside with a blank, wide-eyed stare. He says the hospitalization and the near-death experience remain the deepest source of shame he has faced, but also a turning point that made him realize he needed to change his life forever.\n\nBorg's memoir is packed with a string of episodes that have never before been disclosed in detail. It portrays the pressure of living in his own shadow and the human cost of a life lived in the fast lane of sport, fame, and fortune. It also sheds light on personal relationships, including his long path through marriage and the challenges of parenting while navigating the limelight. In describing these episodes, Borg emphasizes that his drug problems did not define him, even as they reshaped his understanding of home, purpose, and family. The book's revelations come as fans and analysts continue to reassess how a towering figure in tennis balanced genius with the vulnerabilities that accompany extraordinary pressure in the modern era of professional sports.
