Race condition
A race condition or race hazard is the behavior of an electronics, software, or other system where the system's substantive behavior is dependent on the sequence or timing of other uncontrollable events. It becomes a bug when one or more of the possible behaviors is undesirable.
Going (horse racing)
The condition of a race track plays an important role in the performance of horses in a race. The factors that go into determining race track condition include the surface conditions, type of surface, and track configuration. The surface conditions are influenced by the type of surface factoring in soil type, and if the track is dirt, turf, artificial surface; plus surface density, porosity, compaction and moisture content.
