The UNOH 175 was a NASCAR Camping World Truck Series race held at New Hampshire Motor Speedway in Loudon, New Hampshire from 1996 to 2017. Since 2013 it was held the day before the Sprint Cup Series Sylvania 300, the second event in the Chase for the Sprint Cup. The race was 200 laps in length from 1996 until 2010, when the distance was shortened to 175 laps. After a two-year absence from the 2012 and 2013 Truck Series schedules, it returned to the series schedule in 2014. On March 8, 2017 it was announced that Las Vegas Motor Speedway would get a second Cup date, second Xfinity date, and second Truck date. The Cup and Truck races that will be given to Vegas will come from New Hampshire, making the 2017 running the last race. From Wikipedia
