The great virtual match race

Zenyatta and Rachel Alexandra have been dominating on opposite sides of the country, and now they will finally face off.

One is a five-year-old Eclipse-winning champion, unbeaten in 10 lifetime starts.

The other is a nationwide sensation after defeating the colts in the Preakness Stakes, a monster 3-year-0ld filly many say is the best since Ruffian.

The race...

...just happens to be at two separate tracks.
