Triathlon in Tokyo

Triathlon in Tokyo (TnT) is a group of amateur multisport athletes based in and around Tokyo and across Japan. We take part in everything from sprint through to iron-distance triathlon, as well as duathlon, aquathon, and swimrun. TnT welcomes athletes of all abilities, from complete beginners to veterans. Many new members have progressed rapidly from their first Olympic distance triathlon to full Ironman in just one or two years. Members have competed at the ITU Age Group World Championships and the legendary Kona Ironman.
