Formula 1's shorter Grand Prix races will last one season under the FIA's approved rules, with the standard distance returning in 2028.

The normal minimum will fall from approximately 190 miles to 180 miles in 2027, a reduction of about 9.3 miles. The sporting regulations published on Monday include an approved change restoring the longer distance the following year.

That makes next season's reduction a temporary measure rather than a permanent shortening of Formula 1 races.

The FIA linked the cut to changes in fuel flow when the Formula 1 Commission agreed the 2027 package in September. It described the shorter distance as corresponding to a reduction of two or three laps.

The number of laps will still depend on the circuit. The rule sets a distance threshold, with the scheduled race comprising the least number of complete laps needed to exceed it. A shorter lap therefore produces a different lap count from a longer one.

Monaco retains its separate provision, with races scheduled over the least number of complete laps exceeding approximately 162 miles.

The 2028 restoration appears in the section covering approved changes for subsequent years, under Article B2.5.2 on race distance. It restores the same standard threshold used before the 2027 reduction.

The distinction matters when assessing the sport's revised engine rules. Next year's shorter races are part of that transition, but the published regulations already provide for the normal distance to return a year later.
