When we see him run, if he overshoots, we see him just run around the world again. However, has there been any moments where we see him run backwards? Is he able to maintain the same speeds that he does when he runs forward?
6...Wouldn't simply turning around and going back be faster than going all the way around the world? Even for the Flash that just seems like a waste of effort.– Darrel HoffmanJun 16, 2020 at 13:30
1If he can run around the world in less than 90 minutes, then he'll be running at greater than orbital velocity. How can he "run" if he can't touch the ground? Also, even if it takes him 90 minutes to go all the way around the world, he would be running at more than twenty times the speed of sound. He would need Super Strength, to do that, and he also would need to be Super Fire-proof.– Solomon SlowJun 16, 2020 at 18:31
9@SolomonSlow: Like many superheroes, the Flash has a lot of required secondary powers. You'll break your brain if you try to work out all the implications of making his primary power not be suicidal in one way or another.– ShadowRangerJun 17, 2020 at 0:21
5@SolomonSlow you forget the crucial part of any flash answer: Speed Force– CBredlowJun 17, 2020 at 1:56

I can only reinforce Laurel's offering.
The panels below are taken from Brave & Bold #67 (1966), with a recuperating Flash showing the villain what speed is really all about!
He does in the comics:
(Presumably, it’s the same as anyone else running backwards: it’s not as fast as running forwards, but it’s much more showy.)
I believe this image is from the JLA/Avengers crossover.
(Related: In another story the Flash is outsped by some other guy running backwards.)
It is for a fact from the Avengers/JLA crossover epic.– BlazeJun 15, 2020 at 23:42
Is he actually running backwards here, or coming to a halt while turning around? Jun 16, 2020 at 7:46
@Mast Probably the latter; if he came to a halt over water he'd sink in and then have to somehow get out of/above the water again (not impossible but probably something he wants to avoid).– TylerHJun 16, 2020 at 13:29
Not only can he run backwards, he can still outrun Superman while doing so. We see this in the race scene from Smallville.
