Challenge Turku Triathlon 2026

Challenge Turku Triathlon is a summer race weekend in Turku, Finland, featuring the Middle Distance as its main event: a 1.9 km swim, 90 km bike, and 21.1 km run, the same format known as Half-Iron or 70.3. The programme also offers shorter options for newer and younger participants, including a 300 m swim, 10 km bike, and 3.5 km run Super Sprint, alongside Junior Challenge races with child-and-adult and youth categories. The participants represent a diverse group of triathletes. Pro men and women, age-group athletes, relay teams, elite Super Sprint racers, juniors, and parent-child pairs compete over the same weekend. The Middle Distance includes prize money and qualifies for PTO World Ranking Points. The event is also part of the T100 Age-Group Racing series, meaning Turku caters to both competitive racers seeking rankings and local families trying a short-format triathlon.
