I don't know how to make a players speed equal to a leaderstat?

Hi there, I'm having a problem making a players speed equal to a speed leaderstat.

So here i have made a leaderstat for the players speed.

game.Players.PlayerAdded:Connect(function(player)
    local stats = Instance.new("Folder")
    stats.Name = "leaderstats"
    stats.Parent = player

    local SpeedValue = Instance.new("IntValue")
    SpeedValue.Name = "Speed"
    SpeedValue.Value = 2
    SpeedValue.Parent = stats
end)

Here i have made it so when a player activates a tool, a remote event is fired (It also has a cooldown script)

local cooldown = false


script.Parent.Activated:Connect(function()
    if cooldown == false then
        cooldown = true
    game.Workspace.MainEvent.AddSpeed:FireServer()
    script.Parent.Enabled = false
    wait(1.2)
    script.Parent.Enabled = true
    cooldown = false
    end
end)

And here i have made a script inside of the Workspace(with the remote event inside of it named "AddSpeed").

script.AddSpeed.OnServerEvent:Connect(function(player)
    player.leaderstats.SpeedValue.Value = player.leaderstats.SpeedValue.Value + 1
end)

This code does work as i can see the speed going up when I activate the tool. The issue i am now having is linking up the speed leaderstat with the players humanoid speed value. I was just wondering if somebody could give me a brief example on how i could do this?
