Doesn't mean it isn't true, and it would be surprising.

Often people in the manic phase kick out enough energy to run a lot farther than 3 to 5 miles, a whole lot more.

Now, people as depressed as these get would have a hard time running to the bathroom, let alone 3 to 5 miles. There may be something in there.

Bi-polar disease is frequently misdiagnosed. One would have to check the DSM-IV to get precise, but generally to mood changes need to take place over weeks and months. Often-times a rapid-cycling mood disorder is confused by laymen as bi-polar. It is bi-polar, just not Bi-polar.

Especially when younger the episodes can be spaced a ways apart. It might be that someone had a few cycles, enough to be diagnosed, and then started running in between. It would seem as if they were "cured".

And, maybe they were. I dunno. Seems odd, though, considering how active all people seem to be in the manic phase.
