What makes it so annoying to me is that a sprint implies putting in maximum effort for a short time. The pace of a sprint is unsustainable over more than a few seconds.

If you say you did "sprints" for over a year... no you didn't. Either you sprinted for a little bit and then had to walk for a while because you'd used up all your energy. Or, you jogged at a sustainable pace for a year and just called it a sprint.

Oh absolutely. It wasn't even close to being sparkling chaos, let alone Agile. What we had as 'sprints' would be more accurate as Epics. The whole thing was insane but they stuck with the terminology...
