Chilean bodybuilder Marianne von Gierke, a two-time Mr. Olympia competitor, died in the early hours of Wednesday, October 14, 2026, in Punta Arenas, Chile. She was 40, and her death came less than three weeks after she recorded the best finish of her career at the 2026 Mr. Olympia in Las Vegas.
The bodybuilding community is mourning the death of Marianne Von Gierke, a Chilean IFBB Pro League athlete who passed away at the age of 40, with her death confirmed on Wednesday, October 14. Her passing was announced by fellow Chilean bodybuilder Felipe Isaac Fierro in a joint social media statement with NPC Worldwide Chile.
A Sudden Collapse in Punta Arenas
According to Chilean regional outlets, von Gierke's husband drove her to a local clinic late on the night of October 13 after she suddenly lost consciousness, and emergency room staff were unable to revive her despite attempting resuscitation. Her death is reportedly being investigated, with an autopsy expected to determine the exact cause.
The cause of the bodybuilder's death has not been disclosed yet. Regional outlets reported that she died outside Magallanes, though multiple Chilean reports place her death at a clinic in the Magallanes capital of Punta Arenas itself, where she had long lived and trained.
From Law School to the Olympia Stage
A Pioneer for Southern Chile
Originally from Chile's Magallanes region, von Gierke was also a lawyer, and she earned her professional bodybuilding status in 2021 after years of competing in the sport. She began competing in bodybuilding in 2014 and built a parallel career as a fitness trainer and online coach while practicing law.
She made her Mr. Olympia debut in 2024, placing 16th after winning that year's Vancouver Island Pro in Canada to qualify. That first trip to the Olympia stage made her one of only a handful of Chilean women ever to reach bodybuilding's top professional tier.
A Career-Best Season in 2026
Von Gierke secured her return to this year's Mr. Olympia by winning the Women's Physique division at the Rising Phoenix Arizona Pro on Aug. 22, 2026, earning a perfect judging score of three to finish ahead of Winsome White and Sarah Crail, after placing sixth in the category at the Texas Pro earlier in the season. That victory sent her back to Las Vegas for a second Olympia appearance.
Von Gierke's death came roughly two to three weeks after she competed on bodybuilding's premier stage in Las Vegas, where she finished in 13th place in the Women's Physique division at the 2026 Mr. Olympia in late September, improving seven spots on her 2024 result and closing out the best season of her career.
Tributes Pour In From the Bodybuilding World
NPC Worldwide Chile said in a statement, “Today we bid farewell with deep sorrow to an athlete who left an indelible mark on bodybuilding,” adding that she would be remembered for her dedication, discipline and the legacy she built in her category.
“Today we bid farewell with deep sorrow to an athlete who left an indelible mark on bodybuilding.”
Von Gierke's death has prompted an outpouring of condolences from the bodybuilding community, particularly in her home country of Chile. Her law school at the University of Magallanes, where she graduated in 2004, also paid tribute to her as both an athlete and an attorney.
Family and What Comes Next
She is survived by an 11-year-old son and her partner of 10 years, Juan Cofré García. Chilean reports indicate her funeral services were scheduled for Friday in Punta Arenas, the southern city she represented throughout her competitive career.
Her death adds to a difficult stretch for the sports world in recent weeks. American audiences have also been processing the recent passing of Chicago Bears coaching legend Mike Ditka, longtime college coach Dennis Franchione, and pro wrestler PAC, each loss drawing tributes from across their respective sports.
Von Gierke's story also resonates with fans who followed the broader buildup to this year's Mr. Olympia week in Las Vegas, an event that drew attention across combat and strength sports in the United States, much like the packed autumn calendar that has included everything from the ATP Tour playoffs to marquee NFL matchups. For now, the bodybuilding community in Chile and internationally is left mourning an athlete who reached the sport's biggest stage twice and was still improving when she died.
