Anybody know the Etymology of the word 'Sprint' as in coding Sprint?

[Laura Creighton]

I think it comes from Jeff Sutherland's Agile Programming Methodology,
called Scrum http://jeffsutherland.com/scrum/index.html where work is
planned into month long interations called Sprints.  (Jeff must have
terrific stamina if he thinks that the thing to call a month-long race
is a Sprint :-) )

These days we do them shorter -- as in a 4 days Sprint before Pycon.

Anybody know the etymology for sure?
