The 10 Days of Thunder at Charlotte Motor Speedway are far from a break for the NASCAR Sprint Cup Series, but it does provide the opportunity for drivers to hit the reset button.  The Sprint All-Star Race is a relatively short feature.  The proximity to most of the driver's residences in the Charlotte area allows for a few restful weeks (unless your significant other just had a baby, in the case of Kyle Busch and Brad Keselowski).  And, this week's qualifying was run on Thursday in advance of Sunday night's race.

It's go time now, though.  The upcoming race will be a 600-mile marathon, the longest race in the sport by 100 miles.  This grueling test will help set the stage for the second half of the regular season leading up the the Chase.

Here's a look at three drivers to keep an eye on in the Coca Cola 600:

Green Flag - Jimmie Johnson

Johnson's win in this race last year put him alone on the leaderboard with seven career wins at Charlotte Motor Speedway (and that doesn't even include the four All-Star Races he's won at the facility).  Consider him a heavy favorite in this one.

Yellow Flag - Kasey Kahne

Kahne has been all over the map this season, but he seems to be good for at least one win per season, enough to qualify for the Chase.  This could be it.  He has four career wins at Charlotte and finished second in both races at the track two years ago.  He also looked to have a strong car in last weekend's All-Star Race, so that could bode well for him.

Red Flag - Kurt Busch

Busch has looked pretty strong since returning from his suspension, but his stats are not favorable at Charlotte.  In 29 career starts, he's managed just seven top-10s and an average finish of 19.4.  A strong showing in this race will go along way toward illustrating Busch as a top contender in 2015.
