KB Down = Set Voided (Marathon/Half Marathon)

IKMF International Kettlebell Marathon Federation

If the athlete puts the kettlebell(s) down before the set time is over during marathon (60 min) or half marathon (30 min), the athlete is disqualified and the score becomes 0. This is the defining rule of IKMF marathon: the entire result is voided, not just a penalty. Additionally, throwing or dropping a kettlebell intentionally results in instant disqualification, including at the termination of the set.
