An aid station is a designated location, typically along a race route or in a disaster area, where medical professionals and volunteers provide assistance and support. There are several synonymous terms used to describe these stations depending upon the context, including first-aid post, medical station, emergency response station, rest stop, and support station. In some cases, aid stations may also be referred to as checkpoints, aid posts, or rest areas. Regardless of the terminology used, the primary purpose of an aid station is to provide essential services and care to those in need, whether it be a injured runner or a disaster victim.
