Kurt Busch continued his strong run of form at Daytona by winning the first Gatorade Duel on Thursday.

The first Duel set the qualifying order for the inside row/odd-numbered positions of Sunday's Daytona 500. ordinarily that would have put Kurt Busch in third place for the start, but with polesitter Dale Earnhardt Jr. heading to the back of the field before the green flag after wrecking his main car in Wednesday's practice, Kurt will now be at the head of the inside row and effectively inherit pole position.

The position bump filters all the way down the field, so Regan Smith, Kevin Harvick, Matt Kenseth and Kasey Kahne, etc. will be starting from 3rd, 5th, 7th and 9th respectively. Each Duel race also decides the final two qualifiers for the Daytona 500, and in Duel 1 the honours went to Bill Elliott and J.J. Yeley.

In the second Duel, Jeff Burton claimed victory by narrowly beating his team mate Clint Bowyer to the finish line, while Brian Keselowski was propelled through the field to 5th place by his better known younger brother, NASCAR regular Brad.

The second Duel sets the outside row/even-numbered positions, but Jeff Gordon had already secured the head of that row with his performance in the Sunday qualifying session, so that means Burton will start from 4th place with Bowyer, Michael Waltrip and Kyle Busch starting 6th, 8th and 10th respectively.

Waltrip's strong Duel performance qualifies him for the Daytona 500 in his own right, which frees up one of the two remaining starting slots for Dave Blaney; Brian Keselowski is the other driver to gain a starting spot for the Great American Race following the Duels.
