How to speed up character by tapping a button

Hi, I want my character to move faster when the player taps a button and the faster the player taps the faster the character moves. How would I achieve this? I have set up the buttons to work when tapped and not when its held by using a timer.

The code I have so far is:

void ABaseCharacter::Tick(float DeltaTime)
{
	Super::Tick(DeltaTime);
	AddMovementInput(GetActorForwardVector() * axis);
}
void ABaseCharacter::StartMovement() // Called on Button Start
{
	FTimerDelegate TouchTimerDelegate;
	TouchTimerDelegate.BindUObject(this, &ABaseCharacter::EndMovement);

	TapCount++;
	if (TapCount == 1)
	{
		axis = 1.0f;
	}
	GetWorld()->GetTimerManager().SetTimer(TouchTimerHandle, TouchTimerDelegate, 0.1f, false); 

	
}

void ABaseCharacter::EndMovement() // Called on button released or on timer end 
{
	TapCount = 0;
	GetWorld()->GetTimerManager().ClearTimer(TouchTimerHandle);
	axis = 0.0f;
}
