A parsec is a unit of distance. Then again, they never really explained exactly what a "kessel run" was.

In a book they described it as a particularly hazardous area of space that most people went well around. Hence the straighter paths were more dangerous and his was a particularly short path.

Kessel was also referred to by C3PO -
being forced to work in the spice mines of Kessel.

That's the first explanation I've seen that actually makes sense. Thanks!
