Next Stop is Chicago for Sunday’s My A-Fib Risk-dot-com 400 by Janssen, the opening race of the 2015 Chase for the NASCAR Sprint Cup. For The Sixteen Challengers about to embark on a road that will ultimately lead to a championship for one, the countdown starts once again this weekend with 3,595.48 “Miles-2-Miami.”

The ten-race title series will conclude in mid-November at Homestead-Miami Speedway. Hendrick Motorsports’ Jimmie Johnson is the top seed with four wins during the regular season, a total matched by Kyle Busch and Matt Kenseth. Regular-season points leader and defending Sprint Cup champion Kevin Harvick enters the post-season as the Number-5 seed … The next three races comprise the Challenger Round of the post-season, after which the bottom four drivers will be eliminated from championship contention.

Any one of The Sixteen Challengers that wins a race at Chicagoland Speedway, New Hampshire or Dover will automatically advance to the Contender Round of the Chase that opens October 10th in Charlotte.
