When you register Howrse horse for a race what do you do after?

Once your horse is over the age of 3, you may fit it with a saddle, bridle, and horseshoes. Your horse has to have these items to enter competitions.
Once you have given your horse the items, scroll down until you see a box the the right side of the screen that says "competitions".
Open the box and it will say "races", "show jumping", "cross country", and "barrel races".
Pick the one you wanted to enter your horse in, and it will take you to a different page.
The page will ask which horse you want to enter in the competition, and, depending on what competition you want to enter, it will ask you what skill level/what kind of competition you want to enter. Once the contest starts, it will tell you what place your horse got in that competition.
