Strong emotions, endurance, and versatility. These are three key ingredients that define the 2026 edition of the 100 x 100 Half. It is one of the most important events in triathlon—five races and a single way to experience this magnificent sport.

Participants will have to demonstrate their skills in swimming, running, and cycling to be the best on a course that passes through various iconic locations across Catalonia.

One of the defining features of the 100 x 100 Half is that it is a non-drafting competition. This means that during the bike segment, participants cannot ride in a pack to benefit from reduced resistance and must maintain a minimum distance. Additionally, the cash prizes go to the clubs rather than being distributed individually.
