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 a 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 principles of Agile.
