NASCAR announced Wednesday the stage lengths for each race for the 2018 season, including both tripleheaders at Las Vegas Motor Speedway.

The Stratosphere 200 NASCAR Camping World Truck Series race stages will be 40-80-134 for Friday, March 2, while the March 3 Boyd Gaming 300's stages are set for 45-90-200. The March 4 Pennzoil 400 presented by Jiffy Lube will feature stage breaks at 80 and 160 laps, with the checkered flag coming on lap 267.

The MENCS and NXS stage lengths mirror those from 2017, while the NCWTS stages have been adjusted for this season. The same stage lengths will be utilized for Las Vegas' second tripleheader weekend Sept. 14-16, which culminates with the MENCS Playoffs-starting South Point 400.

"Our primary goal every season is providing the best race for our fans, and to that end, we will remain consistent in terms of stage lengths for the majority of our national series events," said Scott Miller, NASCAR senior vice president of competition. "Last year's debut of the race format was a strong one, and we look forward to building on that foundation in 2018, starting with Speedweeks at Daytona."
