F1正赛为何是305公里？1950至2027年赛程距离演变
F1正赛距离由超过305公里所需的最少圈数决定，摩纳哥以260公里为例外；从1950年无统一标准到1989年确立305公里规则，2027年标准将降至290公里。
为什么F1正赛长度为305公里？从1950年到2027年的比赛距离
305公里、两小时，或包含中断在内的三小时：F1比赛距离受明确规则约束。我们解释这些规则自1950年以来如何演变、为什么摩纳哥是例外，以及为什么2027年比赛将变短。
一场F1大奖赛的赛程超过305公里。更准确地说，一场比赛由超过305公里所需的最少圈数构成。唯一的例外是摩纳哥，其最低距离为260公里。
实际比赛时间还有两小时限制。如果比赛中断，包含中断时间在内的总时长不得超过三小时。这是现行F1规则的规定。
但情况并非一直如此标准化。在世界锦标赛的最初几十年里，一些比赛的赛程几乎是现在的两倍。而到2027年，距离将再次缩短。比赛实际持续多久以及完成多少圈，也在我们的文章《一场F1比赛持续多久？》中有所说明。
1950年代：比赛长达500公里
1950年F1世界锦标赛开始时，并没有标准的比赛距离。组织者在很大程度上可以自由决定自己赛事的长度，导致差异相当大。
在银石举行的史上第一场世界锦标赛比赛跑了70圈、325公里。冠军尼诺·法里纳用时2小时13分钟完成。相比之下，在蒙扎的赛季收官战中，法里纳跑了80圈、约504公里。他驾驶了将近三个小时。
更长的是印第安纳波利斯500，从1950年到1960年计入世界锦标赛。它共200圈、805公里，至今仍是世界锦标赛历史上圈数和距离都最多的比赛。
1958年，管理机构引入了更严格的限制。比赛距离被设定在300至500公里之间，最长时限为两小时。
在随后的几年里，大多数大奖赛的赛程在300至400公里之间。上限最终定为400公里。
1971年：最长约322公里
1971赛季，最大比赛距离从400公里降至约322公里。比赛因此明显变短。
同一赛季有一个极端例子。在纽博格林北环举行的德国大奖赛仅持续了12圈。由于赛道长度近23公里，这仍是正常完成的世界锦标赛比赛中圈数最少的。
在1970年代和1980年代，大多数比赛稳定在约300至320公里。
1989年，比赛距离被标准化为最低305公里。目的是确保比赛能在两小时内完成。
此后，每场大奖赛都由使总距离刚好超过305公里所需的最少圈数构成。这一基本原则至今仍然有效。
例如在2026年，这意味着在赛道长度超过七公里的斯帕-弗朗科尔尚为44圈。巴库为51圈，雪邦为56圈。摩纳哥圈数最多，为78圈。
摩纳哥例外：为什么比赛只有260公里
摩纳哥是唯一不适用305公里规则的赛道。这个公国的比赛为78圈、约260公里。
原因是速度。这条街道赛道仅长3.337公里，而且狭窄多弯。平均速度远低于其他赛道。
因此，在摩纳哥跑超过305公里可能会因平均速度低而导致比赛异常漫长。这就是摩纳哥最低比赛距离为260公里的原因。
2011年加拿大站：迄今为止最长的F1比赛
多年来，只有对实际比赛时间的两小时限制。没有规则规定计入中断后比赛可以持续多久。2011年加拿大大奖赛后，这种情况改变了。
蒙特利尔的大雨使比赛中断了约两个小时。简森·巴顿最终在一次惊人的逆转后获胜。官方比赛用时为4:04:39.537，成为F1历史上最长的比赛。
FIA迅速作出回应。从2012年起，包含中断在内的比赛不得超过四小时。实际比赛的两小时限制仍然保留。2021赛季，总时限被缩减为三小时。
2021年比利时站：最短比赛和新积分规则
2021年在斯帕-弗朗科尔尚，F1经历了相反的极端情况。持续降雨意味着车队只在安全车后绕行。官方成绩中仅计入一圈。
根据当时有效的规则，仍然授予了半分。这引发了广泛批评。
因此，自2022年起，对于缩短的比赛，只要在无安全车或虚拟安全车的情况下完成至少两圈，积分便按滑动比例授予：
两圈至比赛距离的25%：前五名获得积分（6-4-3-2-1）。
25%至50%：前九名获得积分（13-10-8-6-5-4-3-2-1）。
50%至75%：前十名获得积分（19-14-12-9-8-6-5-3-2-1）。
自2023年起，当暂停的比赛恢复后，即使最终未完成全部预定距离，也授予全额积分。
部分比赛周末在大奖赛之外还设有冲刺赛。冲刺赛约100公里，约为正常比赛距离的三分之一，通常持续约半小时。
没有强制进站。前八名获得积分（8-7-6-5-4-3-2-1）。2026年赛历中有六场冲刺赛。该赛制的完整细节可在《F1冲刺赛：你需要知道的一切》中找到。
从2027年起，标准比赛距离将从305公里降至290公里。据FIA称，这相当于减少约两到三圈。
F1委员会已批准这一缩减，但仍需FIA世界汽车运动理事会最终批准。

与此同时，目前对受中断影响比赛的三小时总时限将被废除。取而代之的是，将为比赛活动的结束引入固定的硬性截止时间。实际比赛的两小时限制将保留。
英文原文
Why is a Formula 1 race 305 kilometres long? Race distances from 1950 to 2027
305 kilometres, two hours, or three hours including interruptions: Formula 1 race distances are governed by clear rules. We explain how those rules have evolved since 1950, why Monaco is an exception and why races will become shorter in 2027.
A Formula 1 Grand Prix is more than 305 kilometres long. More precisely, a race consists of the minimum number of laps required to exceed 305 kilometres. The only exception is Monaco, where the minimum distance is 260 kilometres.
There is also a two-hour limit on actual racing time. If a race is suspended, the total duration including the interruption may not exceed three hours. That is what the current Formula 1 regulations stipulate.
But it has not always been this standardised. During the first decades of the World Championship, some races were almost twice as long. And in 2027, the distance will be reduced again. How long a race lasts in practice and how many laps are completed is also explained in our article How long does a Formula 1 race last?
The 1950s: Races of up to 500 kilometres
When the Formula 1 World Championship began in 1950, there was no standard race distance. Organisers were largely free to determine the length of their own events, resulting in considerable variation.
The very first World Championship race at Silverstone ran for 70 laps and 325 kilometres. Winner Nino Farina completed it in 2 hours and 13 minutes. At the season finale in Monza, by contrast, Farina raced for 80 laps and around 504 kilometres. He was behind the wheel for almost three hours.
Longer still was the Indianapolis 500, which counted towards the World Championship from 1950 to 1960. At 200 laps and 805 kilometres, it remains the race with both the highest number of laps and the greatest distance in World Championship history.
In 1958, the governing body introduced much tighter restrictions. Race distances were set at between 300 and 500 kilometres, with a maximum duration of two hours.
In the years that followed, most Grands Prix covered between 300 and 400 kilometres. The upper limit was eventually 400 kilometres.
1971: A maximum of around 322 kilometres
For the 1971 season, the maximum race distance was reduced from 400 to around 322 kilometres. Races consequently became noticeably shorter.
One extreme example came that same season. The German Grand Prix on the Nürburgring Nordschleife lasted just 12 laps. With the circuit measuring almost 23 kilometres, it remains the lowest number of laps in a regularly completed World Championship race.
During the 1970s and 1980s, most races settled at around 300 to 320 kilometres.
In 1989, the race distance was standardised at a minimum of 305 kilometres. The aim was to ensure that a race could be completed within two hours.
Since then, each Grand Prix has consisted of the minimum number of laps required to take the total distance just beyond 305 kilometres. The basic principle remains in place today.
In 2026, for example, that means 44 laps at Spa-Francorchamps, where the circuit is more than seven kilometres long. Baku has 51 laps and Sepang 56. Monaco has the highest lap count at 78.
The Monaco exception: Why the race is only 260 kilometres
Monaco is the only circuit where the 305-kilometre rule does not apply. The race in the Principality covers 78 laps and around 260 kilometres.
The reason is speed. The street circuit is only 3.337 kilometres long, as well as being narrow and twisty. Average speeds are considerably lower than at other circuits.
Covering more than 305 kilometres in Monaco would therefore risk producing an exceptionally long race because of the low average speed. That is why Monaco has a minimum race distance of 260 kilometres.
Canada 2011: The longest Formula 1 race to date
For many years, there was only a two-hour limit on actual racing time. There was no rule governing how long a race could last once interruptions were taken into account. That changed after the 2011 Canadian Grand Prix.
Heavy rain stopped the race in Montreal for around two hours. Jenson Button eventually won after a spectacular comeback drive. The official race time was 4:04:39.537, making it the longest race in Formula 1 history.
The FIA responded quickly. From 2012, a race including interruptions could last no more than four hours. The two-hour limit on actual racing remained in place. For the 2021 season, the overall limit was reduced to three hours.
Belgium 2021: The shortest race and new points rules
Formula 1 experienced the opposite extreme at Spa-Francorchamps in 2021. Persistent rain meant the field only circulated behind the Safety Car. Just one lap was included in the official classification.
Under the rules in force at the time, half points were nevertheless awarded. That prompted widespread criticism.
Since 2022, a sliding scale has therefore applied to points awarded for shortened races, provided that at least two laps have been completed without the Safety Car or Virtual Safety Car:
Two laps to 25 per cent of the race distance: points for the top five (6-4-3-2-1).
25 to 50 per cent: points for the top nine (13-10-8-6-5-4-3-2-1).
50 to 75 per cent: points for the top 10 (19-14-12-9-8-6-5-3-2-1).
Since 2023, full points have also been awarded when a suspended race is resumed, even if the full scheduled distance is ultimately not completed.
Selected race weekends also feature a Sprint alongside the Grand Prix. It covers around 100 kilometres, roughly one-third of the distance of a normal race, and usually lasts around half an hour.
There is no mandatory pit stop. Points are awarded to the top eight finishers (8-7-6-5-4-3-2-1). Six Sprints feature on the 2026 calendar. Full details of the format can be found in Formula 1 Sprint: Everything you need to know.
From 2027, the standard race distance is set to fall from 305 to 290 kilometres. According to the FIA, that equates to around two or three fewer laps.
The Formula 1 Commission has approved the reduction, although it still requires final approval from the FIA World Motor Sport Council.
Kimi Antonelli, Mercedes, Max Verstappen, Red Bull Racing, Lando Norris, McLaren
At the same time, the current three-hour overall limit for races affected by interruptions is set to be abolished. Instead, a fixed hard stop will be introduced for the end of racing activity. The two-hour limit on actual racing time will remain.
