There is plenty to talk about ahead of this weekend’s IndyCar race at Pocono, but most of the attention is drawn from the track to some other types of rivalries.

First of all the weekend at Pocono begins on July 4th, Independence Day in the United States, and be sure the American drivers would like to set off the fireworks with an unforgettable win in Pennsylvania.

Then, also on Friday, rivalries will spark between Colombians and Brazilians with a World Cup semifinal at its core. National allegiances have placed Verizon IndyCar Series driver Helio Castroneves of Brazil and his girlfriend, Adriana Henao of Colombia, on opposite ends of the pitch.

“I have a match every day of my life with Adriana – in a good way,” the three-time Indianapolis 500 champion said. “Colombia is playing very well, but I’m telling her it’s the last opportunity to watch them play in the World Cup.”

The barbs are likely to be flying also between drivers at a “watch party” in the Pocono Raceway paddock. Brazilians Castroneves and Tony Kanaan will be in the minority. Verizon IndyCar Series drivers from Colombia are Castroneves’ teammate and Florida neighbor Juan Pablo Montoya, Sebastian Saavedra, Carlos Huertas and Carlos Munoz. Colombians already send a pretty strong signal on how determined they are by sweeping race 1 podium at Houston, so expect tough times for Castroneves and Kanaan at the party.

Will the national rivalries end with the referee’s whistle? Or will there be some revenge from the losing side on Pocono’s tri-oval?

And what about you? Who are you supporting?
