The Duel at Daytona
qualifying auto races to the Daytona 500
The Duel at Daytona, formerly known as the Twin 125s and currently known as the America 250 Florida Duel at Daytona for sponsorship reasons, is a NASCAR Cup Series preliminary event to the Daytona 500 held annually in February at Daytona International Speedway. It consists of two 150-mile (240 km) races, which both serve as a qualifying race for the Daytona 500. The finishing order in the two 150-mile (240 km) races, held on the Thursday before the Daytona 500, determine the starting lineup for the Daytona 500 held on race day.
Qualifying for the Daytona 500 is unique in NASCAR. Only the two front row starters (the pole and "outside pole") are determined by the standard knockout qualifying system. For all other drivers it only determines their starting position in their Duel, with odd placed cars being entered into the first Duel and even placed cars going in the second. After the top two positions are locked in, the next 30 places of starting grid of the Daytona 500 are set by the finishing order of these two races with the top 15 (excluding pole winner and outside pole) making up the next 15 places on the inside and outside lanes respectively. After the Duels are completed the four fastest non-qualifiers by time and finally the six or seven (if no past champion's exemption is needed) highest-earning teams in points (from the previous season's standings) not in the race yet advance (also set by time), and the starting grid for the Daytona 500 would then be set. The order is still subject to change if technical regulations are violated.
History
The event began as twin 100-mile (40-lap) races. From 1959 to 1971, the races were counted with points towards the Grand National championship.

Why this record matters
The phrase “qualifying auto races to the Daytona 500” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 3, 2026. The linked authority identifier is Q378806. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1959 and 1971.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
