At a glance
Why is the 2011 Canadian Grand Prix remembered as both Formula 1’s longest race by elapsed time and Jenson Button’s last-lap win? Torrential rain stopped the race for more than two hours, and six Safety Car appearances repeatedly reshaped the order. Button made six pit-lane visits—including one drive-through penalty—fell to last place, then passed Sebastian Vettel on lap 70 to win by 2.709 seconds.

Why did a 70-lap race take more than four hours?
The official classification records 70 laps and a total time of 4:04:39.537 for Button. That number includes the red-flag suspension after torrential rain made conditions unsafe. It is elapsed event time, not four hours of continuous green-flag racing. The FIA described the stoppage as roughly two hours and noted that the duration prompted a change to the sporting regulations. The record is therefore a caution against comparing race duration with an uninterrupted Grand Prix as if the cars had run at race speed throughout.
The six Safety Car appearances are another distinct measure. They describe neutralizations, not six separate red flags or six pit stops. Formula 1’s race retrospective identifies them as a record at the time and counts Button’s drive-through as one of his six pit-lane visits. The pit-stop summary separately records his tyre changes, so the categories need to be kept distinct.
Six pit-lane visits comprised five tyre stops and one drive-through; the latter is not a tyre stop.

How did Button turn it around?
Button started seventh. His afternoon included contact with McLaren teammate Lewis Hamilton, a clash with Fernando Alonso that left Alonso out and Button with a puncture, and a drive-through for speeding behind the Safety Car. Formula 1’s retrospective records him running last on lap 40. After the restart and a late change in conditions, he moved back through the field and passed Vettel on the final lap. The victory was not a simple result of making more stops: each visit had a cause, and the changing weather and neutralizations altered the strategic picture for everyone.
The official pit summary lists his five tyre-related stops on laps 8, 19, 35, 37 and 51; his lap-13 visit was the drive-through. Counting all six as “pit stops” obscures the difference between changing tyres and serving a penalty. That distinction is useful when comparing strategy totals across races.
What does this race’s record mean?
The Canadian Grand Prix remains the longest World Championship race by elapsed duration in Formula 1’s official record. The unusual total was driven by the red-flag delay, not an unusually long circuit or a 70-lap distance beyond the scheduled 305.270 km. Its six Safety Car appearances and six winner pit-lane visits add useful context, but they are specific records from one event, not typical benchmarks for modern wet races.
