Entries for the contest, in which a lucky fan will split a $5 million jackpot with 2011 Indianapolis 500 winner Dan Wheldon should he win at Las Vegas Motor Speedway, will close at 11:59 p.m. ET on Oct. 6. The winning entrant will also receive a trip to Las Vegas to watch Wheldon compete in person.
The odds won't be in Wheldon's favor as he'll start the 200-lap race from the rear of the star-studded field of 34 cars in the No. 77 Bowers & Wilkins car jointly entered by Sam Schmidt Motorsports and Bryan Herta Autosport with Curb/Agajanian.
But if Wheldon takes the checkered flag, he and the sweepstakes winner will pick up their checks in Victory Circle.
"When you look at the depth of the field it's going to be incredibly tough," Wheldon said. "I feel we'll have a very fast race car. I think we learned (at Kentucky) over the weekend that you need everything right to be able to move forward. We need to work on the race car's balance a little bit. Vegas is going to be a totally different track and I think it's going to be more Texas-like."
