Armor from knights depending on the era and location could weigh up to a 100 lbs. you're not running a marathon in that, short bursts maybe but even then you're not going to have much speed. Even in 20-30 lbs you're going to have issues running, as for swimming forget about it, most people can barely even swim properly let alone swim with weight on them. A marathon runner that wore armor would be slower than hell, they're used to not having any weight, drag perhaps but weight no..a pro swimmer again same concept, they don't swim with weight, drag yes.
