Iron Butt rallies are unique opportunities for riders to pit their wits against each other by juggling the time / distance equation to achieve the maximum possible points from ‘bonus locations’ provided by the Rallymaster.
IBA UK runs three rallies – the Brit Butt Rally (36 hours), the Brit Butt Light (12 hours) and the Iceni Rally (8 hours). IBA UK is closely associated with IBA Ireland and other joint rallies are organised occasionally, e.g. the Wolfhound. All IBA rallies are rigorously validated to ensure that riders have fully complied with the Rallymaster’s rules (however bizarre they may seem at times!).
