Lauren Grüniger

Career At ten years old in 2017, Grüniger attended a training camp in Moscow. She asked her parents if she could stay to continue training. After a long discussion, her father agreed to let her live there with a host family, as the training conditions were better there than in Switzerland; for example, there was ample access to training areas with sprung floors that reduce the impact of jumps, while there was only one intermittently available in Switzerland. She attended a German school and continued to train in Moscow through at least the end of 2021. Grüniger spoke positively about her experiences training in Russia.

In 2022, she competed in the junior event at the Irina Cup, which was used as a selection event for the European Championships by the Swiss Gymnastics Federation. She won the bronze medal in the ball final. She was selected for the junior team at the European Championships and competed with ball only; she was 24th with that apparatus, and she and her teammates placed 18th in the team competition.

At the Swiss National Championships, she won the senior title and three of the four event finals. In June, she competed at her second European Championships, where she placed 30th in the all-around qualifications and narrowly missed qualifying to the final. She said afterward, "Of course I'm disappointed, but I'm also proud of my performance." She also competed at the 2025 Summer World University Games in July, where she placed 12th in the all-around.

She was selected to represent Switzerland at her first World Championships in August 2025, and ahead of the Championships, she trained in Germany. At the World Championships, she placed 30th in the all-around qualifications.

A week later, she won another bronze medal in the all-around at MTM Tournament in Ljubljana.

Grüniger competed at the 2026 European Championships in May, where she had a goal of placing in the top 30; she did so by finishing 25th. In June, she retained her title at the Swiss National Championships and also won all four apparatus finals.
