Dover International Speedway’s 50th Anniversary celebration reaches a milestone this week on July 6, marking exactly 50 years since the first NASCAR Cup Series race on the world’s fastest one-mile oval began.

In recognition of this important date, the Monster Mile announced a special $50 offer in honor of the track’s 50th birthday, in preparation for the Oct. 4-6 NASCAR tripleheader weekend. Children 12 and younger cost $35.

As part of its birthday week celebration, Dover International Speedway is offering a $50 flash sale for Oct. 6, featuring one Monster Energy NASCAR Cup Series playoff race ticket, a FanVision and a Trackside Access pass. The offer is available through July 6, the 50-year anniversary of the “Mason-Dixon 300” NASCAR Cup Series race, the Monster Mile’s first event, which NASCAR legend Richard Petty won by six laps.

Dover International Speedway will be the 10th track in the U.S. to host 100 or more NASCAR Cup Series races.

Dover Downs Hotel & Casino will provide a free fireworks show at about 8:30 p.m. July 5 in celebration of Independence Day.
