Javelin technique and the UK club rules on throwing

Javelin is the odd one out among the throws. Discus and shot put use a spin or glide within a small circle; javelin uses a sprinting run-up, which is exactly why it is the one throwing event where athletes wear spikes.

Grip

The javelin is held at the cord grip with one hand, using one of three common grips: the Finnish grip (index finger behind the cord), the American grip (thumb and index finger pinching the cord), or the V-grip (the javelin resting between the first two fingers). Whichever grip is used, the javelin is carried above the shoulder with the tip angled slightly down and forward throughout the run-up.

The run-up and release

A straight sprint of roughly 10 to 15 strides builds horizontal speed, similar to the start of a 100m. Over the final 4 to 6 strides, known as the impulse stride or crossover phase, the thrower rotates their hips sideways to the direction of the throw while drawing the javelin back with a straight arm, converting that running speed into throwing power at release.

The rules that make it different

The javelin must be thrown overhand, over the shoulder or upper arm, with the arm and javelin staying above the shoulder throughout the throw. No sidearm slings, spins, or underarm releases are allowed, unlike discus or hammer. For a throw to count, the tip must strike the ground before any other part of the javelin, and it must land inside the marked sector. Gloves are not permitted, and tape on the fingers is only allowed to cover an open wound.

Why UK clubs are strict on supervision

UK Athletics' Rule 107 sets out clear safety guidance for clubs, schools and competition providers running throwing events. Every thrown implement, javelin included, has the potential to cause serious or fatal injury if not properly managed, so throwing areas are always supervised, with clear sector control and a strict one-thrower-at-a-time approach. Age group implement weights are set by UK Athletics and get lighter for younger age groups, so always check your own club's current weight for your age category rather than assuming a senior implement applies to you.
