He does have some speedfeats without the hammer, but most of them are quite old. I was the one to bring this one up while searching for information to use for a mod-ruling, waaaaay back when, but Pendaran explains it best. He also has other feats like 'running through a park so fast nobody can see him and think only a that a strong breeze has blown through'.
Again, these are old feats.
Once in a while, in slightly more recent times, we get stuff like 'by narration, reacts in microseconds' and things like that.
