Anna Kiesenhofer

Kiesenhofer studied mathematics at the Vienna University of Technology (2008–11), completing her Master's degree at Emmanuel College, Cambridge (2011–12).^[4] She earned her PhD at the Polytechnic University of Catalonia with her thesis on Integrable systems on b-symplectic manifolds in 2016.^[5] From 2017 to 2021 Kiesenhofer was a postdoctoral researcher at the École Polytechnique Fédérale de Lausanne (EPFL) and was part of a group researching nonlinear partial differential equations which arise in mathematical physics.^[6] Kiesenhofer has authored several scholarly journal articles including:

Kiesenhofer participated in triathlon and duathlon from 2011 to 2013. After an injury, she had to limit her running and therefore concentrated on cycling from 2014. She joined the Catalan team Frigoríficos Costa Brava – Naturalium. In 2015 she entered the Tour de l'Ardèche but she was the victim of a fall on the first stage. She failed to recover and after several difficult stages decided to withdraw.^[7]

In 2016, she won the Coupe d'Espagne.^[8] In September, she took part in the Tour de l'Ardèche in the international team. On the third stage, the first breakaway started at the 12th kilometer. It was composed of Dani Christmas, Anna Plichta, Sara Olsson, Vita Heine and Silvia Valsecchi. Twenty kilometers away, they were joined by Kiesenhofer. In the descent of the pass of Murs, the groups were seven minutes and twenty-five seconds ahead. After Blavac, Anna Plichta went off alone and she had a lead of a minute thirty at the foot of Mont Ventoux. On the ascent, Kiesenhofer joined her. She won the stage by almost four minutes over Flávia Oliveira and she took the lead in the overall standings.^[9] The next day, Flávia Oliveira escaped in turn and she took Kiesenhofer's pink jersey.^[10] She kept her second place in the overall standings until the end of the race.^[11]

In July 2021, as Austria's sole representative in the 137 km-long Olympic women's road race in Tokyo, Japan, she won the gold medal, crossing the finish line 75 seconds in front of Annemiek van Vleuten of the Netherlands.^[2][12] Kiesenhofer trained for the event without a coach or a professional team, and was not viewed as a contender to win a medal.^[12][13] In the race, she initiated a breakaway from the start, and was joined by four other competitors.^[12] With 86 km to go, the leading group, now down to Kiesenhofer, Omer Shapira, and Anna Plichta, formed a 10-minute advantage over the chasing peloton.^[2] Kiesenhofer broke away by herself for the final 41 km while climbing the Kagosaka Pass, dropping Shapira and Plichta, who were later caught by the peloton.^[12][14] Many in the peloton, including silver medalist Van Vleuten who celebrated mistakenly thinking she had won the gold,^[15] finished the race unaware that Kiesenhofer was still in front of them.^[14] Kiesenhofer later said she "couldn't believe" she won adding that she would have been happy with a top 25 finish.^[16]

After racing as a privateer in 2022, Kiesenhofer rode for Roland Cycling team for the 2023 and 2024 seasons.^[1][17][18] In 2025, she joined Team Picnic PostNL as a trainer.^[19]
