NASCAR Xfinity Series Race Today: Martinsville start times, schedule and how to watch live on TV

The 2025 NASCAR Xfinity Series hits Martinsville Speedway today (Saturday, March 29) for the US Marine Corps 250.

Last time out at Homestead, Justin Allgaier took the victory, earning his second consecutive Xfinity Series win after a dramatic late overtime battle with Sam Mayer. The No. 7 car's victory came against the odds, too, with Kyle Larson having dominated in Florida last Saturday and led 132 of the 201 laps of action.

Last weekend is now well behind us, however, with the race today around the 0.526-mile track today set to offer a unique challenge, with just 12 degrees of baking on the turns and a track surface that is asphalt in some places, and concrete in others.

Just who will come out on top remains to be seen. There have been five different winners in the Xfinity Series so far this season - Allgaier in the last two races, preceded by Aric Almirola, Connor Zilisch, Austin Hill and Jesse Love - and the remaining drivers in the field would love to extend that list to six names.

With that said, let's take a look at all the details you need to know ahead of today's race, including how you can watch all of the action live.
