Early Life and Chilean Roots
Marianne Belén von Gierke Barassi grew up in Magallanes, one of Chile’s most southern and isolated regions. She often described herself as “magallánica de corazón” — a Magellanic at heart. After earning her law degree in Ciencias Jurídicas y Sociales from the Universidad de Magallanes (class of 2004), she balanced a professional legal career with her passion for fitness.
She began competing in bodybuilding in 2014 and became the first woman from Magallanes to seriously pursue and represent Chile in the sport. Her Chilean identity remained central throughout her career; she consistently competed under the Chilean flag in the IFBB Pro League’s Women’s Physique division.
Rise Through the Professional Ranks
Von Gierke earned her IFBB Pro card in 2021 after strong amateur results, including overall wins at NPC events in the United States. From there she steadily climbed the pro ranks, competing in Canada, Puerto Rico, and the U.S.
Key milestones included:
- 2024 Vancouver Island Pro – 1st place (Women’s Physique), earning her first Olympia qualification
- 2024 Mr. Olympia – 16th place
- 2026 Texas Pro – 6th place
- 2026 Rising Phoenix Arizona Pro – 1st place (perfect score), securing her second Olympia invite
- 2026 Mr. Olympia (Las Vegas, late September) – 13th place
These results made her one of Chile’s most successful female professional bodybuilders and a clear national ambassador for the sport.

She shared training updates, legal insights, and personal motivation on Instagram (@mari.gierke.ifbbpro). In the final weeks of her life she remained active online, posting gym content shortly before her passing.
She died in the early hours of October 14, 2026, in Punta Arenas after being rushed to Clínica RedSalud Magallanes. No official cause has been released as of October 16, 2026, though early reports mentioned a possible sudden medical event. NPC Worldwide Chile and the Chilean bodybuilding community issued immediate tributes, highlighting her passion, discipline, and the inspiration she provided to athletes across South America.
Why Her Chilean Nationality Mattered

Fans and fellow athletes repeatedly noted how proudly she carried the Chilean flag and how her story encouraged others from similar backgrounds.

Marianne von Gierke’s nationality was Chilean — specifically rooted in the Magallanes region — and she remained a proud representative of Chile until the end. In a career that combined law, coaching, motherhood, and elite competition, she proved that determination can bridge remote origins and the world’s biggest stages. Her 2026 Rising Phoenix victory and improved Olympia placing stand as lasting highlights. The fitness community continues to honor her memory in the days following her October 14, 2026, passing.
