One of the founding principles of the [Agile Manifesto][1] is

> Agile processes promote sustainable development.  The sponsors,
> developers, and users should be able  to maintain a constant pace
> indefinitely.

Scrum teams use the term "Sprint" to refer to an to the work cycle (also known as an iteration).

However this doesn't make sense to me. According to google a sprint is:

> run at full speed over a short distance.

In other words it's not sustainable. Why do Scrum teams use the word "Sprint"? It appears to me to conflict one of the basic principals of Agile.
