About the Event

Kujukuri Triathlon, 99 tri for short, is one of Japan's largest triathlons. Kujukuri Triathlon is known to be the "perfect triathlon for beginners" (and those seeking PBs!) due to the nature of the course. The toll roads used for the bike route are a straightshot with few sharp curves and the breezy shoreline on the run course is flat. The half Ironman / middle distance at the Kujukuri Triathlon continues for round two this year!

Kujukuri Beach is located in Chiba Prefecture and is easily accessible from Tokyo (just an hour and a half away by car!). It is known for its year round water activities, such as surfing and jet skiing. It s also known as Japan's second longest beach. Registration fee includes the finisher's BBQ party. Come and enjoy fresh grilled hamaguri (Japanese clams) and other famous local dishes before heading back to Tokyo!

* Please note that 70.3 and Olympic Distance participants registered through Samurai Sports should collect their race packet on Saturday. We will make exceptions, but you must email us beforehand.
