How do you get the horse in the Legend of Zelda orcarina of time

Come back to the Lon Lon Ranch as Adult Link and pay Ingo (the guy that keeps charge of rides with Epona) about 50 or 60 rupees to race him, if you win, Ingo locks you in Epona's stable and it's pretty easy to get out because it's a short fence. (Foolish Ingo.) Jump off the fence if I had to remember and BINGO! You can ride Epona almost anywhere but if you want to ride Epona again, use Epona's Song on the Ocarina of Time. You may have got this before you beat the game where you learn it from Young Malon when you use Link as a kid.
