Change label of "Sprint" to "Hike", or a word that suggest something less hectic.
The word "Sprint" suggests a hectic time within a Sprint timebox.
We coach teams to act professionally, slice work into smaller pieces and work with sustainable pace towards the Sprint goal. This contradicts with 'sprinting'.
For people outside of a Scrum Team it sends the message of busyness.

How about "Iteration" - which implies that further iterations will build on what has already been delivered. This might discourage the "6 month Gantt chart" multi-sprint planning as well!
Sprint really sucks as a name though. Sprinters by definition leave nothing in the tank, and expend all their energy in an initial burst of unsustainable energy. Sprinters physically go into anabolic respiration, leaving themselves a debt of oxygen, and needing slow down or stop to recover; is it any wonder that Scrum sprints often result in rushed implementations and technical debt, go slower and slower, and eventually end up with "refactoring sprints" or bug bashes to recover?
