I’m a fan of 24-hour endurance races in motorsports. Since 2020, I’ve been contesting the true-24 race run by the 24 Hours of Lemons, first as a part of another team, and since 2021 with our own car. Here’s our 1999 Miata endurance car showing off its fancy lights:

One thing I’ve noticed is that it can be hard to find lists of all of the true-24-hour (or longer) races. To my knowledge, there are currently 10 such races for cars and at least 5 for motorcycles, though I know that my list of motorcycle races is definitely incomplete. Here are the races I’m aware of:

24 Hours of Daytona – January – GT and prototype cars – Daytona International Speedway (road course), Florida, USA – IMSA

24H Dubai – January – GT cars – Dubai Autodrome, Dubai, UAE – 24H Series

Now, all of this isn’t to take away from the other great endurance races of the world, such as the Baja 1000 or the Dakar. Those simply aren’t 24-hour races in the sense meant here. Also, I’m vaguely aware of at least several karting 24-hour endurance races, but I’ll admit that I haven’t looked into them in depth yet.

Know of a true-24-hour (or more) motorsport race (even karting!) that I didn’t list here? Email me! I’ll update this list as new information comes to my attention.
