The Javelin Throw requires a number of things to be right to get those long distances. But these are my Top 5 of things that you need to start throwing:
1. A Javelin

Of course! You can’t throw a javelin without a Javelin. If you are only starting out, you should check with your local athletics teams. Being able to use a club's Javelin not only saves you forking out for your own but will also enable you to get started quicker and get a feel for the event.
If you do wish to buy your javelin I highly recommend a Nordic – the BEST brand in the World for Javelins!!! There are other makes like Sandvik which are high quality also. If you are just a beginner you needn’t worry too much about this.

When choosing a Javelin to buy or use (whether in training or competition) there are two major considerations:
• The correct weight for your age group/gender. The standard weight for women is 600grammes and for Men is 800grammes. Javelins are also generally available in 400, 500 and 700gram weights also. Some stockists also have special children's sizes and foam training aids which (look a bit like 3 foot rockets but) can be used INDOORS! Make sure you train with the correct weight or come competition day and you will be at a HUGE disadvantage!
• International standards. The main concern here is centre of gravity. Some older models of Javelin are not approved for competition as their centre of gravity is different. Always check the competition rules AND double check that the javelin has a little sticker that usually says IAAF Approved.

2. Javelin SPIKES
These are your throwing shoes! Heel spikes are VITAL in order to avoid slipping and to generate the thrust you need when planting your foot. Without spikes in the heel you risk SLIPPING which can be very dangerous with enough momentum behind you and particularly if there has been any rain. Some equipment stockists sell a heel clip like below, which you can attach to normal running spikes. This is a very economical solution if you already have a pair of spikes.

3. Coordination
Unlike our hammer, discus and shot putting counterparts, we do not rely so much on strength and muscle as coordination and rhythm! It is the combination of many many little things that makes the Javelin go further! Being able to combine all these little things will get that Javelin going further.

4. Rhythm
A full throw contains a number of steps and requires your body to be in tune with a number of points. Having natural rhythm or developing your rhythym makes this so much easier.

5. A Routine
Every athlete needs a training routine. It should not be sooo repetitive that you get bored but it should enable you to work on the different aspects of the throw and developing the right types of muscle in a structured way. Repetition of the little things regularly will program them into your body and make them soo much easier to achieve naturally when you are throwing.
Some of these steps are clearly easier to follow than others! If you need further information please ensure that you seek out complete and accurate information. This will avoid risking injury. Only take advice from coaches or athletes with real practical experience in this event.
