Were medieval gauntlets seen in First Knight a type of military/war training? Or is this Hollywood nonsense?

I've asked this before and didn't get a lot of traction, but https://www.youtube.com/watch?v=x1SXJh2f2ng

Shown above. Is this obstacle course-type, gauntlet/contraption realistic? Would the real version have been for training purposes? A spectacle for "fun" like shown in the film?
