On a more personal note, while I don't feel too sorry for Frank in light of his continual doubling down on the lies, I do have to wonder if, in addition to narcissistic reasons, Frank misses actually being able to keep up with the kids he coaches. I have little doubt that he was a runner of basic talent at an earlier age, and my coach used to tell us that he would never have us do a workout he couldn't do. We called him on it once, and he kicked our asses. So, I bet Frank could run with his kids at one point. Hell, in my case, my kids' high school coach had me show up on occasion to put the hurt to the young whippersnappers to teach them pacing and maybe a little respect for their elders. But as the years add on, I'm realistic about my ability to keep up with the kids. Maybe Frank couldn't let that one go. Kinda like the old sled dog axiom--if you're not the lead dog, the view is always the same. I don't wish Frank any ill will. In fact, had LAM disqualified him quickly, I probably wouldn't have cared at all. But Ed Whitlock is a hero to me and probably most older runners, and I don't want his legacy to be in any way marginalized by someone like Frank.
This is probably the most sympathetic and charitable explanation for Frank's behavior and for why anyone should care about the truth getting widely publicized. I believe Frank deserves to reap what he sows and I hope that non-runners understand that this matters.
