Elbow pain is the most common injury in the javelin, and it is usually trying to tell you something about your technique, not just your training volume. The throw puts enormous stress on the inside of the elbow, and a few specific faults multiply that stress until the joint complains. Fixing the mechanics protects the elbow far better than icing it after every session. Here is what causes the pain and what to change. None of this replaces a sports-medicine professional, so if it already hurts, get it looked at.
The classic javelin elbow injury comes from leading with the elbow, letting it drop below the shoulder and pull through ahead of the hand. That low, rounded position puts the inside of the elbow under huge tension. The elbow should stay high, at or above shoulder height, with the throw coming over the top.
If the javelin is launched by the arm alone instead of a whip that runs from the legs and trunk through a relaxed arm, the elbow absorbs force it was never built to take. A proper throw cracks like a whip with the arm last and loose. An arm-only throw hammers the joint every rep.
Volume and implement weight matter. Ramping hard throwing sessions without a base, or training with a javelin that is too heavy, overloads the elbow before the tendons adapt. Build throwing volume gradually, use age-appropriate weights, and treat pain that lingers as a stop sign, not a toughness test.
Whether your elbow drops is hard to feel and easy to see. Film a throw from the side, the AI tracks your elbow height relative to your shoulder through the release and flags the low, leading position that loads the joint. Seeing it is the first step to fixing it before it turns into a real injury.

Keep the elbow at or above shoulder height and throw over the top, and the load stays manageable. Let it drop below the shoulder and lead ahead of the hand, and the inside of the joint pays for it.
