After Saturday night's NASCAR Sprint Cup Series race at Bristol Motor Speedway spilled over into Sunday afternoon due to multiple rain delays, teams had to quickly turn around and head to Chicagoland Speedway for an organizational test session.

The test was supposed to be held over the course of Tuesday and Wednesday, but due to the threat of weather on the second scheduled day, NASCAR made the call to hold one session from 9 a.m. to 9 p.m.

Jimmie Johnson noted just how long of a day it was coming off of a long weekend at Bristol.

A rainy weather forecast for the next 2 days meant a 12 hour test session today @ChicagolndSpdwy. 😳

Crew guys are my hero. #ThankYou
