A standout field lines up for the Yotta XP Menton on October 10
On October 10, Menton will host the YOTTA XP for the first time. The event challenges athletes to complete as many swim and run loops as possible within a time limit that shrinks with every lap. Triathlons.com takes a closer look at this innovative format, launched in Vichy in 2022 and arriving on the Côte d’Azur in 2025.
After its first Côte d’Azur edition in Cannes in 2025, YOTTA XP is heading to Menton this year for its second event on the French Riviera, backed by the Alpes-Maritimes department. Plage des Sablettes will be the starting point for a day built around pushing personal limits, with the Mediterranean as the athletes’ playground.
Known for its colourful façades, authentic atmosphere and famous Lemon Festival, Menton offers a distinctive backdrop for YOTTA XP. Just a few kilometres from the Italian border, the city is also expected to attract plenty of competitors from across the frontier, adding to the international feel of the event.
A new challenge with every lap
Created in Vichy in 2022 by Sacha Rosenthal, CEO of Xefi and an accomplished IRONMAN triathlete, YOTTA XP offers a unique format in the world of multisport: repeating swim and run loops within a time limit that gets shorter and shorter.

In Menton, participants can choose from several formats depending on their level and ambitions: YOTTA XP S, S Relay, M and M Relay, bringing experienced athletes and newcomers together for the same unique experience.
Format | Swim | Run | Maximum loops |
Yotta XP M | 400 m | 4 km | 5 |
Yotta XP M Relay | 400 m | 4 km | 5 |
Yotta XP S | 200 m | 2 km | 5 |
Yotta XP S Relay | 200 m | 2 km | 5 |
Yotta Run | 1 + 2 km | 5 |
More than €33,000 in prize money for the top athletes
