Martinsville Cup race to feature full field

Preliminary entry lists have been released for this coming weekend’s Sprint Cup-Camping World Truck Series doubleheader at Martinsville Speedway. On the Cup side, there are forty drivers heading into the first short-track weekend of the year – marking the first time there’ll be a full field of cars since the season-opening Daytona 500 last month. Kyle Busch and Kyle Larson are the only two who have signed up for double duty – driving in both Saturday’s Alpha Energy Solutions 250 Truck Series race and Sunday’s S-T-P 500.
