Hello PMC!!!
Today I have for you: Faster Sprinting!!!
It allows you to sprint faster without affecting your regular walk speed. It is very useful for adventure maps that require a lot of traveling.

To get started type this command in chat:
Next, get a repeating always active command block and paste in this command:
Lastly, put a chain, unconditional, always active command block and paste in the last command
And you are done! Whenever you sprint, you will now sprint considerably faster.
If you are using this for an adventure map and don't want the player to take advantage of it, you might want to set a potion block up. Check out this tutorial if you want to do that.

Be sure to leave a diamond, perhaps even a favorite if you are feeling generous, and if possible, maybe subscribe. Thank You, and stay tuned for more!
