IKMF competition rule. Athlete Rights, Duties & Conduct category.
In marathon and half marathon, if an athlete puts the kettlebell down before the time is over, the athlete is disqualified and the score becomes 0. Throwing or dropping a kettlebell intentionally also results in instant disqualification, including at the termination of the set.
