NASCAR Cup Series teams are set to participate in an organizational test this week at Martinsville Speedway.
Teams will plan to be on track from 9 a.m. to 4 p.m. ET both Tuesday and Wednesday at the .526-mile Virginia oval. The sessions will be a key tune-up before the Cup Series returns Oct. 30 for the Xfinity 500 (2 p.m. ET, NBC, NBC Sports App, MRN, SiriusXM), the next-to-last event of the season and the deciding race that will lock in the Championship 4 field.

A Goodyear tire test was held at Martinsville at the end of June, with Kyle Busch, Austin Cindric and Tyler Reddick — one driver representing each manufacturer — participating. NASCAR officials said no technical changes are planned for the two-day test this week, and that teams will use a new tire based on the findings from the Goodyear session.
