Full contact 24 hours non-stop Ninjutsu Sparring

The "24" is an intense sparring marathon designed to push us to our physical limits. We've managed to successfully complete four of these events, and countless 12-hour ones. Weather conditions forced us to cut two "24" short at around the 14 and 15-hour marks. Each event kicked off in the late afternoon and ran continuously until the same hour the next day. We gave ourselves a brief 5-minute break every hour for hydration, stretching, refueling, and quick medical attention. After the break, it was back to sparring with a new partner for another hour.

In 2003, we aimed for a spot in the Guinness Book of Records. To meet their criteria, we had notary witnesses, continuous video documentation, and all the necessary legal and medical precautions. However, an unexpected November heatwave hit, and the event had to be terminated by the designated medical doctor. Several participants collapsed and required hospitalization, leading us to abandon that year's "24" after 15, very tough hours.

Our specialized fitness routine is the foundation for the physical demands of these events. While we continue to participate in marathons , the "24" remains the most challenging event we've undertaken.

There's no specific reason for engaging in such extreme events, other than the adventure and sense of community accomplishment they provide.
