One of the tightest tracks on the circuit, Martinsville Speedway's pit road is one of the most unique in all of NASCAR. The pit road winds around the track from Turn 3 all the way to the exit of Turn 2, making for close quarters and many chances to find trouble.

Richard Childress Racing's Todd Berrier, crew chief for Kevin Harvick, knows the best way to avoid trouble on pit road is to be the first one in and have a clear shot back to the track. Looking at today's pit road, it is clear the majority of Chase drivers have chosen pit boxes towards the exit of pit road.

"When you're the guys that are running in the front, you're the first to pit, you're the first to leave," Berrier told HardcoreRaceFans.com. "So if you are at the beginning end of pit road and you come in to pit and you go to take off, there's still a line of cars screaming in that have to pit. So, in turn, you just go down as far as you can to try that when you pit and leave all the guys that come in and pit behind you are - the reason the top ten or twelve in points are the top ten or the top twelve are because they're going to run in the top ten or the top twelve. So those guys are going to pit first and they're wanting to get out first. If you pit on [entrance of pit road], you pit first and then you still have cars crossing in front of you, so you just pit as far as you can around to combat that."

With a pit road unlike any other in the sport, pitting at the entrance of pit road is more of a threat than anything else. With a pit wall wrapping all the way around the track, there is very little room for error.

"It's not as big of a disadvantage at a wider pit road then you do here," Berrier went on to say. "If a guys coming in, you still have a lane you can run, here you don't have a lane you can run. There's no room to run three wide."

Currently sixth in the Chase, Harvick and Berrier head into today's event 207 points out of the top spot. Martinsville Speedway has not been one of Harvick's best tracks, but the driver of the No. 29 Shell/Pennzoil Chevrolet remains confident.

"This race is just about surviving the first part of it and keeping the brakes on it and really putting yourself in a position at the end and maintaining your track position all day," said Harvick. "Hopefully we can do that and wind up where we need to be and have a chance at the end."

With track position such a big factor in the outcome of the race, Berrier is focused on giving his driver enough for the end of the run and making the best calls on pit road.

"The biggest concern for today is maintaining enough rear grip late in the run for the car, but it's going to come down to pitting and pit road. When you pit last and hopefully if you don't try to stretch it too far and get too much out of it like we saw in the truck race, I mean Benson won it on four tires, but you could have about done it on no tires. There's a fine line on what lap is too late and what time isn't and you have to pick the right time."

While he admits fuel mileage could be a factor in today's event, Berrier says, "It's not a concern, you just hope you figure right."

With five Chase races down and five left to go, Berrier sees this as almost a brand new Chase. "You just throw caution to the wind and go for what you can go for and go try to win," Berrier explained. "If you win the rest of it will fall and if doesn't, oh well, it doesn't matter you do your best and call it good."
