It won't really matter how much faster the Runner is, because after the Sentry gives him a few heavy bombs to the noggin, it's lights out. Norrins just a super powered wuss, he can't really fight, while Sentry duked it out with a cybernetic organism with computer fast reflexes, and the ability to adapt to almost any given physical threat, and went blow for blow with King Hulk. The Surfer nearly got eaten by Ravenous' mutts, and if not for the power cosmic they would have chewed him up like they were doing to the Gabriel construct.
