How Fast Can The Flash Run

How Fast Can The Flash Run? Speedster Guide (2024)

Most of us know The Flash as one of the fastest superheroes in the world. He can zip around a block and back faster than you can blink your eyes. It is said that even Superman can’t beat the Scarlet Speedster in a race! 

That being said, knowing the exact speed of The Flash is almost a mystery. So, how fast can The Flash run?

We’ve gone the extra mile to find out the answer.

The Flash: How Fast Can He Run?

The comics reveal that The Flash can run 13 trillion times the speed of light.

Unlike The Man of Steel or Wonder Woman (whose powers are inborn), Barry's powers come from The Speed Force. This power allows him to go beyond his physical limit, where he can travel across universes.

Training with a tachyon device helped him hone his superhuman speed to travel to other dimensions, create a time remnant (a close of himself from a potential future), harness kinetic energy, and avoid sonic boom.

In CW's The Flash (starring Grant Gustin), Barry Allen got his abilities when he got struck by a bolt of lightning working in the crime lab of the Central City Police Department.

As a result, he gained super speed, incredible speed thinking, and could calculate faster than a quantum computer, among other powers.

What Is The Top Speed Of The Flash?

Comics

The Flash is the fastest hero in the comics until he sacrifices himself in the 1985's Crisis of Infinite Earths.

Barry Allen is not the only Flash in the comics — Wally West, Barry's sidekick, also known as "Kid Flash," is said to be the fastest Flash. In JLA#89, West had to save an entire city from a nuclear explosion, which led him to transport them to a safe radius at 13 trillion times light speed. 

The Speed Force was shared among three characters: Barry Allen, Jay Garrick, and Wally West. 

Reverse Flash, The Flash's arch nemesis, is also undeniably fast. [1]

Movies

How fast is The Flash in this year's DC Universe movie? We have yet to find out.

However, if we were to base it on 2017’s Justice League, we saw that The Flash's Ezra Miller was faster than Superman at Mach 28 versus the latter’s Mach 27.5. 

In What Episode Has The Flash Ran Fastest?

The Flash ran the fastest in Season 6, Episode 1. Titled “Into the Void,” Barry Allen had to sprint to prevent the immense gravity well from crushing him.

This means Barry was traveling at speeds of at least 670.6 million miles per hour (Mach 874,031) for over 30 seconds.

Flash’s Speed Compared 

Sonic

The Fastest Man would outrun Sonic in a heartbeat. 

Barry Allen is capable of saving more than half a million people from a nuclear bomb explosion. He was able to go in and out of every house and building in the city within the range of the explosion, which required him to travel faster than the speed of light multiple times.

On the other hand, Sonic in the Sega Games was required to outrun a black hole, which meant he had to travel at speeds faster than 186,000 miles per hour. 

Superman

The Flash can run faster than Superman. In the DC comics, it is revealed that there was a point when Barry would let Superman win races on purpose.

He was also seen “panting and disheveled” when he tried to catch up with Barry Allen, Jay Garrick, and Wally West. 

Quicksilver

Quicksilver is The Flash’s counterpart in the Marvel Universe. However, The Flash would outrun him because Barry Allen has access to The Speed Force.

While Quicksilver’s mutant gene gives him incredible speed, his top speed is around Mach 4 to 5, which is just slightly faster than sound at Mach 1.

Can The Flash Outrun Light?

Yes, The Flash can outrun light. His speed can violate the laws of physics and allows him to travel faster than light. 

This means that if light can travel 186,000 miles per second, The Flash can travel 1,750,000,000,000,000,000 miles per second.
