NYTimes: Swim. Bike. Cheat? This is a fascinating story because I do these types of events (albeit much, MUCH shorter distance) and I hate the idea of cheating on them because, as the story says, for most of us cheating on an event is cheating yourself.
But it's also fascinating because, on the one hand, many of the accusations are corroborated by metadata from the ubiquitous digital pictures taken throughout, and on the other hand, the accused could have provided significant data/metadata in her defense from her own GPS devices and hasn't.
