About this event

This is a major event on Sado Island in which over 2,000 people from inside and outside the island participate, racing across Sado Island in three disciplines: swim, bike, and run. On the day of the event, the entire island is enveloped in triathlon excitement, filled with the passion of athletes, supporters, volunteers, and diverse people.

In addition, relay-style Type RA (same distance as Type A) and Type RB (same distance as Type B) are also available. Athlete registration and race briefings take place the day before the event, and exchange events such as the Island Festival party and Matakoiccha party will also be held.
