Ramping Up is an in-game achievement in Run 3.
The only way to finish this achievement is to use the Skater or equip his costume. The Ice Skater is a little better for this achievement, hence the hint. However, it may still be a bit difficult, especially for beginners.
You should try to make your speed as high as possible, then skate on the Ramp. This can let you fly through quite some distance in the air without jumping. However, you need to be slow enough to turn, or else your character may tumble off the platform.
