2 runners swap bibs... get caught. Yes - report them... have their times disqualified.... write a blog about how this type of activity can impact on other runners and the sport - I get that. But the vendetta you have embarked upon to publicly shame and condemn them - and your gleeful "mission" to spread their names and faces, and those of their spouses/partners and children, as far and wide as possible, says a lot more about your character then theirs. Yes they cheated/broke the rules (intentionally for personal gain or for a joke) but the fact you never asked before assuming you knew the only possible reason concerns me. As a doctor I would hope you would have more compassion and empathy then you have displayed... and as a mother I hope you are not teaching your children it is OK to shame, bully and harass others.
