On January 14, 2010 it was announced that due to NASCAR's standard time rule, Phoenix's April race would be extended from a 312 lap to a 375 lap race to guarantee a nighttime finish. The extra 63 laps (100 km) will change the race name to the Subway Fresh Fit 600

NASCAR announced on August 10, 2010, that Phoenix's spring date will move to February beginning in 2010. The race will be reduced back to 500 km in length and will be run the week following the Daytona 500 instead of the early April date the race had occupied since its inception in 2005. Like Phoenix's fall race, the spring race will be run during the day.
