Who We Are

Triathlon in Tokyo (TiT) is a group of amateur multisport athletes based in and around Tokyo. We take part in everything from Sprint through to Iron-distance triathlon, as well as duathlon, aquathon, and swimrun. We have no formal structure, meetings, or meets; instead we organise informal training sessions through our Google Groups forum. We do, however, have a team uniform which is available through the World Triathlon Store, along with a range of team wear. TiT 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 Worlds. If you are interested in joining us, please get in touch through the contact page.
