Write me a lua script for my roblox experience that will allow the character to run faster than the default.
local player = game.Players.LocalPlayer
local character = player.Character
local humanoid = character:WaitForChild(Humanoid)

-- Increase the speed of the character
humanoid.WalkSpeed = 50 -- default is 16

-- Optional: You can also increase the run speed
humanoid.RunSpeed = 100 -- default is 40

This script accesses the LocalPlayer property to get the player's character, and then accesses the Humanoid property of the character to increase its WalkSpeed and RunSpeed properties. The default WalkSpeed is 16 and the default RunSpeed is 40, but you can set them to any value you want. In this case, we have set WalkSpeed to 50 and RunSpeed to 100, allowing the character to move faster.

Note: This is just a basic script and you can further customize it to suit your needs.
