Important Practice Notes
Long Run Speed - Practice at Martinsville can be deceiving, because being fast for one lap doesn't mean much. Instead, you need to analyze long-run speeds by these drivers to determine which ones will actually be fast during the race.
Be wary of relying just on the fastest lap ordering most leaderboards show. There is only 0.111 seconds between the fastest practice lap and the 20th place fastest lap.

Shane van Gisbergen - The No. 97 Trackhouse team had a bit of a scare on the morning of practice, as their battery shorted out everything in the car. The broadcast didn't mention it more than once so it can be assumed that the issue was fixed.
