He explained how the track demands utmost concentration for a prolonged period.Unlike other tracks where drivers usually prefer the inside lane to make overtakes, Darlington allows them to carry more speed on the outside lanes. As a result, drivers often run close to the wall, where even the slightest mistake can prove costly.Reflecting upon the same, Blaney said:“It is a tough place. I think it’s one of the toughest places we go, more mentally than anything for me. How do you stay in it for that long? I feel like the mental mush that your brain is in after leaving that race is pretty high, because your concentration level is at 110 percent the whole time. At some places, you can get in these zones of like a relaxation mode to an extent of getting in your flow and doing things… but I feel like every lap (at Darlington) is just a battle to try to find speed and not find the fence." "There’s less room to work, so I think that’s what makes that place so difficult and the two ends being vastly different is definitely a challenge," he added.Ryan Blaney has never won at the egg-shaped oval. His highest result comes from a fifth-place finish earlier in the season. On other playoff tracks he's worried about, Blaney named Talladega and the Charlotte Roval his top picks.Next, the No.12 driver heads to World Wide Technology Raceway for 240 laps around the 1.25-mile track.
