The 2026 CMAS World Cup Finswimming Indoor will convene the global finswimming community in Aix-en-Provence, France, from April 24 to April 26, 2026. This event — part of the Confédération Mondiale des Activités Subaquatiques (CMAS) World Cup Indoor Series — represents one of the premier competitions in the 2026 indoor pool season and is expected to attract elite international competitors across multiple age and performance categories.
Sport Overview: Finswimming and the World Cup Series
Finswimming is a high-velocity underwater sport in which athletes use fins (monofins or bifins), snorkels, and streamlined technique to cover distances at speeds that outpace traditional swimming. Governed globally by CMAS — the World Underwater Federation — finswimming features competitions both in indoor pools and open water, with world rankings maintained across multiple disciplines and distances.
The CMAS World Cup Finswimming Indoor Series functions as an annual competition circuit consisting of multiple rounds hosted in different international venues. Each round offers athletes the opportunity to compete for points, prestige, and preparation ahead of major championships later in the season, including the CMAS World Championship Finswimming Indoor in June 2026.
Aix-en-Provence: Host City and Venue
Aix-en-Provence, located in the south of France near Marseille, has become a dynamic hub for competitive aquatic sport and cultural tourism. The selection of Aix-en-Provence as the host for a World Cup round underscores France’s growing profile in the finswimming community and offers an attractive setting for international athletes and spectators alike.
While specific venue details and technical bulletins for the 2026 event are pending release by CMAS, it is typical for World Cup rounds to be staged in long-course indoor pools (50 m) equipped with electronic timing systems and configurations suitable for both sprint and middle-distance finswimming events.
Context in the 2026 International Calendar
The Aix-en-Provence round is positioned near the midpoint of the indoor season. Prior CMAS World Cup rounds in 2026 include events such as the Lignano Sabbiadoro World Cup in March, while subsequent highlights for the sport include the CMAS World Championship Finswimming Indoor scheduled for June 2026 (hosted in Incheon, South Korea).
This placement within the broader competitive calendar makes the Aix-en-Provence event not only a standalone opportunity for top-level performance but also an important stage for athletes to refine technique, assess competition, and accumulate valuable experience ahead of the season’s peak events.
As preparations continue and the official documentation becomes available, athletes, coaches, and supporters will look to Aix-en-Provence as a highlight of the 2026 indoor finswimming circuit.
