She is probably sincere in that interview.
However, I don't think a blanket statement should be made that the key to longevity is to move up in distance. I know that had been anecdotally what most distance runners do as they age, but I don't think it is the path to extended success for all distance runners. Some would be better off staying in the best event of their youth.
At the end of the day, if that is what they were built to run, why move up? There is a reason Kim Collins isn't moving up to the 400 and Lagat isn't running the marathon.
Lagat has moved up - he used to be a 15/5 runner, now he's a 5/10 runner. Kim Collins is the exception to just about any rule ever.
As you get older you get slower and stronger. Almost every runner would be better moving up in distance. Going from 8/15 to the marathon is pretty extreme though, and I'd say you're better off sticking closer to your pet event
