As a general rule, the comics claim that
While Quicksilver is often thought of as the fastest of the Avengers, one hero fans know from the movies can actually outrace him when they need to. Many heroes possess enhanced speed, but Pietro Maximoff is generally considered Earth's fastest man (at least in Marvel Continuity).
Captain Marvel
Her powers could not only stand a chance against Superman, but most likely beat him as well.
However, Superman does have the advantage in that he's faster than Thor. Not that Thor is any slow moving slug, it's just there's only one person faster than Supes and that man is the Flash (clearly proved in comic book lore when they race).
The two heroes have raced several times since then, in the comics, cartoons and movies. As a general rule, the comics claim that The Flash is the faster hero, with Barry Allen, Wally West and even an octogenarian Jay Garrick having outrun Superman over the years.

In a competition of speed between the Blue Blur and the Scarlet Speedster, it will take more than math and science to really comprehend their overall speed. However, taking all things we know into account, Flash would win a typical race against Sonic the Hedgehog and come out as the faster of the two.
The most famous of these is the Flash, also known as the Fastest Man Alive. Ever since the days of World War II, there has been a man clad in red who can run at impossible speeds, using his power to save lives and defend those who cannot defend themselves. All between the ticks of a second.
In the series Flash Forward, it was determined that Wally West is the fastest being in the whole Multiverse.
3 Darkseid Has Previously Beaten Superman
If one can deal with his telepathic and telekinetic abilities, they must deal with the Omega Beams and his deadly Life Draining power. Superman can't take on Darkseid alone. The entire Justice League still struggled to face this celestial being.
Scarlet Witch's most important aspect in this fight is that she has the ability to defeat Superman. He is not impervious to magic, so her hits will damage him.
The Man of Steel can only be defeated by Captain Marvel using energy absorption. Captain Marvel, a Kree-Human hybrid, is a cosmic-level superhero who has overcome even greater challenges. Although Superman truly is the pinnacle of strength, if Captain Marvel can find a way to depower him, it's game over for him.
However, the Runner started relying on the power of the Space Gem to improve his already impressive speed. Thanos eventually took the gem from him and left him with nothing but his speed. Still, the Runner is the fastest Marvel character ever and much faster than DC's Flash.
Wally himself has performed several feats and made several references to be faster than Barry and having surpassed him. Wally is fast enough to easily break all the speed barriers and even enter the Speed Force.
Flash would both outrun Quicksilver and defeat him in a battle. Now that we know that Flash is the ultimately faster character than Quicksilver, it's time to analyze why and what makes him stand out when compared to other speedsters in the Marvel universe that come nowhere near his speed.
Like other speedsters, Godspeed can run up to 10 times the speed of light by entering the Speed Force.
Quicksilver. Wanda Maximoff's brother Pietro Maximoff gained his supersonic speed after being exposed to the power of an Infinity Stone. Right from his first appearance in Avengers: Age of Ultron, he's known to be the fastest superhuman with a perceptive mind and quick-witted motion.
Shazam can fly at the speed of light, which makes him faster than almost any other hero, but both Barry Allen and Wally West are able to move at speeds faster than light, meaning that while they would have to push themselves, at least two Flashes are faster than Shazam.
By being able to travel in a dimension where time has been eliminated, Dragon Ball's Goku proves that he is technically faster than even the Flash.
Sonic wins. Quicksilver has hit SoL before, but Omega told Sonic that if he was to accelerate more, he'd hit the speed of light. Sonic has also outran a black hole before, and light can't escape black holes.
While we've established that a number of characters have been a match for Superman, his most notorious defeat is clearly his death at the hands of the monster Doomsday.
When it comes to raw strength, Superman is more likely to outmatch Captain Marvel. Based on how their powers work, Captain Marvel is almost always at maximum capacity with her abilities, whereas Superman can only grow stronger the longer he is under a yellow sun.
In a straight-out race, Flash would win against Superman, although closely. When they raced in the comics, sometimes Flash won, and sometimes it was tied, but Superman never bested him. However, in a one-on-one fight, I think Superman eventually wins simply on durability.
