I found a good breakdown of the all star race thanks to the NASCAR website.  Check it out.

Who is eligible for the All Star Race, a primer on the all-star eligibility…

-        Drivers who have won NASCAR Sprint Cup Series points races in 2012 and 2013

-        Drivers who are past NASCAR Sprint All-Star Race winners in the last 10 years

-        Drivers who are past NASCAR Sprint Cup Series champions in the previous 10 years

-        The top-two finishers in the Sprint Showdown, the 40-lap race that precedes the NASCAR Sprint

-        All-Star Race

-        The top Sprint Fan Vote driver who finishes the Showdown and whose car is in “raceable” condition as determined by the series director per the 2013 entry blank. Fans may vote for their favorite driver by using the NASCAR Mobile ’13 application or online HERE.

Votes cast from the NASCAR Mobile ’13 application count double. 

How do they determine starting line up? 

The need for speed begins Friday night with Coors Light Pole qualifying at 6 p.m. ET on SPEED. Qualifying will consist of three laps and a mandatory four-tire pit stop. Pit road speed, entering and exiting, will not be enforced. The team with the quickest time wins the Coors Light Pole and will lead the field to green on Saturday night.

Whats the format and the prize?:

Like last year, the 2013 NASCAR Sprint All-Star Race will consist of five segments -- four 20-lap segments and a 10-lap shootout. The winner earns a $1 million pay day from Sprint.

But unlike last year, the running order at the completion of the fourth segment (Lap 80) will be repositioned based on the average finish for the first four segments -- putting a premium on strong finishes throughout the entire event. The new lineup will be placed directly behind the caution car prior to the opening of pit road for a mandatory four-tire pit stop, placing a spotlight firmly on the unsung heroes of NASCAR -- the pit crews. The order of the cars returning to the track will determine the starting order of the fifth segment. Running order ties will be broken by the finish of the fourth segment. In the fifth and final segment, only green flag laps will count.

BUT WAIT!! There is More!

This year there is even an added incentive: if a driver wins all five segments, he or she will take home “Bruton’s Big Bonus” -- an extra $1 million paid by Charlotte Motor Speedway and Bruton Smith, Chief Executive Officer, Speedway Motorsports, Inc.

Enjoy the Race,
