To start, this is a secret achievement, so take note of that.

You will need to make sure you have 100% concentration for this one, as you will gain speed and need to correct any mistakes or you will not be able earn this one.

The slide is considerably short, so you don't have to worry about that.

To the achievement, if you take note of the bars, you will be able to avoid them if you make any mistakes, and if you follow the XP coins, you should be able to avoid taking any damage. This will generally take you 3-4 attempts. If you take any damage, make sure you reload the checkpoint before you reach the end, or you will have to re-do the level.

Once you reach the end of the path, you should unlock the achievement, if not, I suggest you restart and try again.
