Then alternatively, he can just tap the speed force and then time has no meaning.
It's not even light speed though. This is more stuff like 3 million times light speed. Flash definitely doesn't do that very often, I don't know if he ever HAS done that, without drawing speed from something else. (Him+ the speeds of Supes, Jay Garrick, Max Mercury, and Jesse Quick probably was something around that... He ended up beating a teleporter from another dimension to Earth) The fact that Surfer and Runner can do those speeds pretty much instantaneaously doesn't help Wally either.
Surfer searched the ENTIRE planet Earthin the time it took Doctor Strange to finish a sentence. The Runner traveled across galaxies in response to Moondragon yelling once. He was there before she finished. The kids are freaking fast.
