The 24 Hours of Spa is an endurance racing event for cars held annually since 1924 at the Circuit de Spa-Francorchamps, Stavelot, Belgium. It is currently sponsored by CrowdStrike.

Endurance racing is a form of motorsport racing which is meant to test the durability of equipment and endurance of participants. Teams of multiple drivers attempt to cover a large distance in a single event, with participants given a break with the ability to change during the race. Endurance races can be run either to cover a set distance in laps as quickly as possible, or to cover as much distance as possible over a preset amount of time.
