Maybe, instead of going faster while in the air, once every 60 seconds (or however long) you can double tap in a certain direction and it will bring you up to full speed (not 100 speed just as high as you have set for it). And if it needs an animation just have a lion appear behind the player (gives them a reason to run).

Reaching max speed in less than 30 frames would be too OP in my opinion.
