Review of the 34th Edition of the La Tour Geneve Triathlon

Record Performance by Nina Derron and Another Victory for Thomas Huwiler


The return of Thomas Huwiler, the event’s patron, was particularly impressive. After a year marked by a serious injury that kept him away from competitions, Thomas Huwiler once again demonstrated his incredible resilience and determination. Following a long rehabilitation process in physiotherapy at La Tour Hospital, his return to competition was marked by an incredible performance. Indeed, the president of the Geneva Triathlon Club won the Half format hands down, crossing the finish line in 4h 01m 53s, almost 10 minutes ahead of his successor. He was greeted by spectators and peers alike upon his arrival at Eaux-Vives.





Meanwhile, Zurich native Nina Derron shone in the women’s category by setting a new event record in the Half format with a spectacular time of 4h 10m 53s. Her exemplary management of each segment showcased both her power and endurance. The Swiss athlete, known for her determination and competitive spirit, exceeded her own expectations and those of the public, etching her name in the history of the La Tour Geneva Triathlon.


The event kicked off with the Standard format on Saturday morning, starting with a 1.5km swim featuring an Australian exit, allowing athletes to enjoy the festive atmosphere along the course, followed by 40 km of cycling and 10 km of running between the Jardin Anglais and the Plage des Eaux-Vives. The day concluded with the Discovery format, an ideal race for beginners to the discipline. Finally, alongside the Half, the Kidsathlon (6-10 years) and Schoolchildren (11-13 years) swam and ran around the Eaux-Vives beach, much to the delight of the parents.


The Short format, however, had to be canceled on the recommendation of the Cantonal Police. In the context of meteorological risks with intense electrical activity possible during the event, the Organizing Committee and operational partners (Cantonal Police, SIS, Civil Protection, 144, Samaritans...) ensured that the safety of participants was their number one priority. Given these weather forecasts and the potential risks of storms and lightning, the decision to cancel the race was made to guarantee the safety of everyone.


This 34th edition would not have been possible without the commitment and passion of the volunteers, partners, local authorities, various administrations, and the entire Geneva community. The Organizing Committee warmly thanks everyone who contributed to making this triathlon an unforgettable moment, despite the very challenging weather conditions.


A Message from the Title Partner

Once again this year, La Tour Hospital is proud to support the event as Title Partner. We offered strength tests and movement analysis with state-of-the-art equipment, as well as sports nutrition advice, directly in the heart of the village. Additionally, an interdisciplinary space bringing together sports doctors, physiotherapists, and nutritionists was available to visitors for sports-medical advice. We congratulate all the participants on their race, as well as the organizers, first aiders, and volunteers for the success of this 2024 edition! See you next year!” stated Boris Gojanovic, Sports Doctor and Head of Health Performance.
