Running in full armor

[jvrjenivs]

This is a difficult question to answer, as you've to take some different aspects of the answer into account.

First, what do you mean by full armour? You mean a first century infantry soldier (so, someone wearing a lorica hamata, squamata or segmentata) with helmet on and big shield in his left hand? If so, from experience I would say that's possible to do for both trained as untrained (but fit) people.

But you have also to take into account what distance you mean and in what kind of circumstances (flat surface of grassland, sand or within a wood?) as this all will influence how fast you will be get tired. Running some distance in armour is good to do, but you get tired eventually. But your amour will not restrict your movement as much that you aren't possible to run. Training will of course increase the amount of time you can run before getting tired, so I would diffentatelly say there is a difference between an trained soldier and a normal civil person. We know the Roman legionaries would undergo a fast amount of training during his time of service.
