The 2018 Pocono Green 250The race logo in 2020 and 2021
The inaugural Xfinity Series race at Pocono was held on June 4, 2016 with a scheduled distance of 100 laps/250 miles (402.336 kilometres).[2] However, the race was shortened after only 53 laps/132.5 miles (213.238 kilometres) because of persistent rain showers. The race marked the first time NASCAR's second-tier series visited and raced in the state of Pennsylvania since the closure of Nazareth Speedway in 2004.[3] The second running of the event was the first NASCAR-sanctioned event at Pocono to use the stage format, a format that was created prior to the 2017 NASCAR season for all three divisions for all race tracks; the 100 laps were split into three stages, with the first two being 25 laps each and the last consisting of the final 50.[4]
In 2020, the distance was reduced to 225 miles and 90 laps—with the first two stage lengths being reduced to 20 laps—as the race was held on Sunday in support of the NASCAR Cup Series' second round of a Pocono doubleheader.[5][6]
In 2022, the race was moved from June to July and the Pocono Mountains Visitors Bureau, which was previously the title sponsor of one of the track's Cup Series races, replaced J.P. Mascaro & Sons as the title sponsor of the race. Like they did with the Cup Series race name, the PMVB replaced their own name in the name of the race with "Explore the Pocono Mountains".[1]
In December 2024, Pocono Raceway's website announced that the race will return to its original distance of 250 miles/100 laps after being 225 from 2020-2024 (partly due to the Doubleheader weekend)
