Also, if getting outed as a cheater in races would ruin your entire life, maybe don't put so much stake in running. It's like a snake eating its tail: the only people who would care enough to cheat in relatively casual races, are the people who care more about their image in such a toxic way that they would rather fake an accomplishment than actually achieve it. Of course this type of person bursts like a balloon when called out - there was never a real life to ruin, just a pathetic person faking race results.
