Finally old enough to pursue her dream, Rainbow Dash parts with her friends and joins pre-season training with the Wonderbolts. Old enemies and new friends come together as she trains, but being a Wonderbolt is about more than just flying faster than the rest. Will Rainbow Dash prove capable of overcoming the obstacles arrayed before her, or will she drop out and become another failed hopeful? There's only one way to find out! Contains some language not appropriate for younger bronies.

EDIT: All instances of "Ditzy" replaced with "Derpy." Her character is more-or-less unchanged from the original upload, though.
