Stand by me? Dillon brothers vie for Richard Childress' attention

Austin and Ty Dillon are the grandchildren of team owner Richard Childress.

And that's where competition between the brothers Dillon starts.

"The funniest thing that happens on the weekend is that my grandfather stands with the brother that qualifies the best," said Austin, who drives the No. 3 Richard Childress Racing Chevrolet for his grandfather in the NASCAR Sprint Cup Series. "That was our deal and we always wanted him to stand with us. He wants both of us to have at least one family member with them before the race."

If that's the case, Childress will be standing next to Austin for pre-race ceremonies after he qualified 15th for today's Food City 500, while Ty will start deep in the field in 35th after spinning and making contact with Landon Cassill during the first round of Friday's three-round qualifying session at Bristol Motor Speedway.

Ty, driving the No. 14 Stewart-Haas Racing car for the injured Tony Stewart at Bristol Motor Speedway, pays close attention to where his brother finishes each race, and vice versa.

"I think we both know about every week, where the other one finishes," said Ty. "We are always paying attention and we are always talking to each other on the weekends to see what we can do to help each other. The ultimate goal is to be racing for wins against each other and if it comes down to that we will both be happy."

Along with the will to help each other, the brothers have another thing in common -- their focus on physical fitness, which will be put to the test at the .533-mile Bristol layout.

"I work out pretty hard in the offseason and do a lot of mountain biking to try and keep up my conditioning," said Ty. "The biggest thing coming in to this weekend was to come in here properly hydrated and prepare to be in the car for almost three days, all day long."

Sunday's race will be Ty's first Cup event at the Tennessee short track, and Austin is already familiar with the challenges that come with 500 grueling miles at Bristol.

"It is definitely one of those places that will wear you down and make you work for it," Austin said. "Ty will get plenty of a taste of it here on Sunday. It's kind of a mentality approach because you go into the race knowing it's going to be a grinder and you have to stay in the race the entire time."
