Wheldon plays down Indy chances

Only radio problems in Japan prevented Wheldon winning all three oval races held so far this season, and he has led 484 of the 700 laps to date.

But he believes that Indianapolis will be much more open than the first four rounds of 2007.

"I think it's difficult to say who is the favorite going into Indianapolis," said Wheldon.

"Do I think I'm going to be a contender? Absolutely. I was very strong there last year. Certainly throughout my career I've been very lucky to be in very competitive equipment to be good at Indianapolis because it is the race that I love.

But I honestly think you could pick 10 to 15 people. That's the thing about Indianapolis.

"I mean, it wouldn't be Indianapolis if it was just one of those races where (only) three or four people could win. It's not. It's one where 10 or 15 could win, and possibly more."

With preparations for Indianapolis lasting several weeks, Wheldon believes that form in the preceding rounds could be largely irrelevant by the time the race starts. He cited the example of 2006 Indy winner Sam Hornish Jr, who has only taken one podium finish so far in 2007, but is expected to be a contender in the 500.

"I think you can create your own momentum because the month is so long," he said.

"I think obviously, you know, Sam's had a disappointing - by his regards - start to the season. But I can guarantee you come race day at Indianapolis, he's going to be strong."

Despite being sceptical about his 'favourite' billing, Wheldon reiterated his determination to take a second Indianapolis win to add to his 2005 triumph.

"The Indianapolis 500 I think, as everybody knows, is the be all and end all to me," he said.

"That's the race that I'm desperate to win. I've had a taste of that milk before.

"It's an amazing thing. You think after winning it once, after you worked so hard to try and win that race, you'd be satisfied. But I think that taste of milk makes you even more determined to win again."
