Treadmill shows medieval armour influenced battles

[Stuart]

There was a program on not so long ago where they looked into this. I think the presenter may have been a chap called Mike Loades, but they gradually trained up a guy until he could handle the armour. Then he took part in combat. He was utterly shattered after 5 minutes of fighting.

That might have been the same program ("The Weapons That Made Britain" ?) that I saw that talked about the Battle of Agincourt itself.
