2. Javelin Throw The javelin throw is the field event where an athlete runs down a narrow runway then tosses a long, spear-like object   of  about 2.5 m (8 ft 2 in) in length, as far as he can into a marked field area.

3. The javelin thrower gains momentum  by running within a predetermined area . Javelin throwing is an event of both the men's decathlon and the women's heptathlon.

4. The javelin used by men must be between 102 and 106 inches long with a minimum weight of 28 ounces. For women, the length is about 87 to 91 inches with a minimum weight of 21 ounces. Women’s and Men’s Javelin

5. Runway Specs The runway must be at least 33 yards and as much as 37 yards long. Two white parallel lines, slightly wider than 4 feet apart, mark the runway. At the end of the runway is an arch-shaped foul line with a radius of about 9 feet.

6. The arc, which is made of wood or some other type of durable material, must be flush with the ground and painted white. The thrower can't touch any of these lines, leave the runway, or the area outside of these lines, before the javelin lands.

7. Equipment Specs The javelin head is made of metal, tapers to a point and is attached to either a hollow or solid shaft. The shaft must have a uniform, smooth surface with no ridges or grooves. The javelin can't have any attachments that can change its center of gravity or throwing characteristics. The cord grip must have a constant thickness and can't be more than .31 inches larger than the diameter of the shaft.

8. The grip of the javelin must cover the center of gravity, which must be between 0.90m and 1.06m behind the tip for men and between 0.80m and 0.92m behind the tip for women.

9. Throwing Technique Proper technique requires the athlete to hold the javelin with only one hand on the cord grip. Gloves aren't allowed, and tape on the fingers is permitted only if its to cover an open wound.

10. Javelin Throw Steps The technique used to throw the javelin is dictated by IAAF rules.

11. The rules do, however, allow athletes to chalk their hands. The javelin must be thrown with an over-the-shoulder motion. The competitor can't turn his back to the throwing area until the javelin is airborne.

12. The landing sector is marked by two radii separated by 29 degrees, extending outward from a point on the runway 8m before the curved throwing arc. The landing sector is marked by white lines measuring 5cm wide, the inside of which is the boundary for fair throws. Landing Sector

13. Legal Throws The javelin must land within the "sector" to register a score. This fan-shaped area extends out from the ends of the arch-shaped foul line. The javelin can't land on the lines marking the sides of the sector. The metal head of the javelin has to hit the ground first or the throw is a foul.
