Edit: The beacon isn't relevant. It's just a red herring, caused by my bias.
Just updated my 1.13 world that has existed in multiple versions. (1.9, 1.10, 1.12.2, 1.13-pre2, 1.13 and maybe others).
Under the effect of the 6 beacon buffs I enter the nether. Running as much as possible, so I get the most distance out of the beacon buffs. I keep the speed increase, even while crouching, even while not sprinting. There is no difference between walking and sprinting either. I seem to be sprinting. Also, the eating sound has sped up, but only when the speed thing happens, so... no separate issue, if that's okay.
Under the effect of the 6 beacon buffs I enter the nether. This time I stand still and wait. All is normal.
Testing in creative default world made specifically to test this bug:
Side effects include:
-buff timer counting twice as fast, buffs not expiring, being stuck at 0 when going out of range of the beacons under unknown, slightly different, but nonetheless common conditions.
--inability to fly in creative when switching from survival while under the effects of this bug- Actually just required pressing space faster, because: jumps also go faster
-dayLightCycle being sped up
-redstone repeaters working faster. Pistons potentially as well. Sticky piston doesn't tire out with 2 repeaters set to 1, even though the game sometimes catches up (doing 10 or so extensions in a lot less than a second)
-falling speed is at 100 blocks/second
It feels like I'm at speed 25 or 50 just from running around the general area in which I built the beacon. Original issue now only occured in the overworld for reasons unknown.
Relogging properly updates the speed back to normal.
Steps to reproduce:
1. Build a 4-level pyramid with 6 beacons on top
2. activate each of the 6 buffs
3. Build a nether portal next to the beacon pyramid
4. While under the effects, go through the nether portal
5. Wait for the buffs to reach 0 seconds remaining (they'll stay at 0 forever at this point)
6. Enter the overworld

Can confirm. I also can confirm, that when you join a world this speed "buff" can happen as well and that is not dependant on Beacons.
I also can add that when on a multiplayer vanilla server, this speed "buff" happens only client-side and server speed is not affected. Other players can see your speed movement. Even though hand animation is affected, the actual speed of eating something is not affected. The same for mining.
During this weird speed movement the server doesn't report "moved too quickly" and doesn't kick for flying or other kind of cheat.
Your movement is sped up as well as falling, climbing ladders, hand animation and speed of jumps.
This probably isn't some Java thing, since the original reporter stated he was using Java 8 and I'm running Minecraft both client and server on Java 10.
(side note: this probably is duplicate to MC-134833)
I have this bug in a very new low-tech game (just a couple days old). I had just started fishing and sleeping in a bed when I saved, reloaded, and started moving very quirkly. No nether, no beacons, not even any diamonds yet. It persists in the saved world. If I go to other worlds, the character moves normally, but in the world with the problem, I can't make the super speed stop.
sorry for the late info, but for those who have only read the changes on reddit, This is a known issue which will be addressed in the next snapshot.
This happens even without a beacon; upon entering the Nether, the game will speed up your movement until you reload the world.
