How fast does Sonic the Hedgehog run?

shadow can run as fast as sonic. which means he runs at speed of sound.

Sonic can run faster than the speed of sound, which is impossible for any human being.

The name of the fast blue hedgehog is Sonic the Hedgehog.

no, they don't. but that would be really cool if they did. =)

Hyper Sonic the Hedgehog is extremely fast! He's faster than the fastest!

sonic is so fast because hedgehogs can run SO fast that there heart beats 120 times in 5 seconds thats why he is so fast.

Sonic is named "sonic" because the word sonic means speed or "fast"! so they bacicaly named sonic fast fast the hedgehog?

sonic is created by SEGA and sonic team makes the games. sonic is a blue hedgehog that can run really fast. he has tons of friends and he always beats eggman

silver, tough he is like sonic an shadow he cant run as fast he a psycic

He could run at sonic speeds.

he's not that fast compared to sonic and shadow which makes him the slowest sonic the hedgehog video game character next to Amy rose

If you have watched the Sonic X episode where Sonic faces off with Shadow, they would be the same speed. Sonic has his shoes that make him run really fast, where shadow's trademark hover shakes propel him at extreme speeds that rival those of Sonic.

sonic his fast and cool like me

Silver the Hedgehog is pretty dang fast, but no where near as fast as Sonic

well sonic was going to be a jack rabbit because their supposed to be fast but they made him a hedgehog

Sonic can run at 3000 kilometers per hour.

The anagram of sonic the hedgehog "sonic the hedgehog."

Amy Rose likes Sonic the Hedgehog! Cause he's fast and saved her millions of times!

Sonic stands for the realy fast hedgehog guy in the Sonic games. OR... It stands for something that is very fast, like supersonic. Ok

Shadow the Hedgehog, If they aren't equal. After that would probably be..... Tails, he has been following sonic for years and has gotten pretty fast, though nowhere near as fast as sonic at full speed.

To run away from Amy :P ^_^ EDIT: Very funny! That, and he's... umm... I dunno... Birth defect? XD

In Sonic 06 (Sonic the Hedgehog) Mach Speed is only usable in a certain stage after your regular speed fails to accomplish your mission, sonic goes to desperate messures and starts going really fast. Such as the mach speed section for wave ocean, Sonic is forced to run super fast to catch up with the Egg Carrier and Save Elise

in Sonic the Hedgehog 1 you can't....only in sonic the hedgehog 2, sonic the hedgehog 3, and sonic & knuckles

Actually, XLR8 moves as fast as the blue blur himself, but he cannot run on terrains Sonic can, so this is a toughie. But in speed wise, they are tied.

sonic >7 AM gotta go fast?
