CONCORD, N.C. — The Coca-Cola 600, the longest race on the NASCAR Cup Series schedule, was postponed from Sunday night until Monday due to wet weather at Charlotte Motor Speedway.
The crown jewel race will begin at 3 p.m. NASCAR has moved the second-tier Xfinity Series race up to an 11 a.m. start Monday; it had been scheduled to run Saturday but was previously postponed.
Cup Series points leader William Byron will start on the pole for the Coca-Cola 600 after qualifying was rained out Saturday night.
It marks the first time the race has been moved to Memorial Day due to weather since 2009. The race is 600 miles over 400 laps and typically takes about five hours to complete. Half of the laps must be completed for it to be considered an official race.
