The Drydene 311 is the second of two NASCAR Cup Series stock car races held at Dover International Speedway in Dover , Delaware, the other one being the Gander RV 400 . It is held on the last weekend of September or the first weekend of October. It is the fourth race in the Cup Series' NASCAR playoffs after the 2018 realignment. NBC has the rights to obtain the final 20 races of the season (14 of 20), including this race. Kyle Larson is the defending winner of the event. In 2020, the race was removed from the playoffs. After initially being planned for the penultimate race of the regular season, the event became part of a doubleheader with the rescheduled spring race in August due to the COVID-19 pandemic . The race length was also shortened to 311 miles for both events.
