It is a good idea to spectate or volunteer at a meet to get a feel for how a contest progresses. It will also give you a chance to talk to those who compete and may be able to offer some friendly advice to a beginner.
If you live in a remote area where few meets are held, if ever, you could try searching at your local library for some decent training information. The internet has a wealth of information–but beware, much of the information you find may not be good advice, or simply the wrong advice for someone at your level. Always proceed very cautiously and keep a critical mind when using any training program.
