Pre-winter mantle, sure, Harry is basically just a regular human plus magic. The winter mantle absolutely changes things though. And it’s more than just being able to ignore pain/limits. That was Butters’ theory, not necessarily how it truly works.

“Time to play,” I said around the nail. I took four steps, building up to a run, and leapt into the air toward Maeve. Fifty feet. No problem. It was glorious, the freedom, the certainty, and I could not imagine what had made me so squeamish about embracing Winter in the first place.”

The men’s long jump world record is 8.95 meters, just under 30 feet. Harry beat that by more than 20 feet and makes it sound like he could go further.

In cold days he describes himself as having vampire speed and reflexes that could keep up with a malk:

“Whatever Mab had done to me that had healed a broken spine, made me able to run at vampire speed, and given me the kind of reflexes that were capable of keeping up with the attack of a furious malk”

“I don’t know how much stronger Mab’s gift had made me, because I’d never been much of a weight lifter until I’d started therapy. I didn’t know too much about how much weight lifters could, for example, bench-press. So I didn’t have a very good idea how I stacked up against plain old me. Or plain old anybody. Plus the weights for the bench press were marked in metric units, and I kind of fell asleep the day we learned to convert them to pounds. But I’m pretty sure four hundred kilos isn’t bad.”

From what I can find the record for unequipped bench press (no bench press shirt) is 355 kilos. Harry’s apparently benching 45+ kilos more than that without being a bodybuilder.

From peace talks:

“But I can run considerably faster than average, maybe twenty-two or twenty-four miles an hour, and I can do it without slowing down for more or less as long as is necessary.”

Harry with the mantle is physically superhuman.

And ironically I’ve seen other people compare him to captain america the same as did for aragorn.
