As of 13 August 2026, AI can only partly analyse your running form.

What to actually do

1. Hand it to a person

   The route this page recommends

   A person who owns the outcome does this end to end, worth it when the failure is dear.

2. Use a tool built for this

   Second choice

3. Do it yourself

   The distant third

   A chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.

   How to actually do it

   1. Open your phone camera and record a natural run from the side, front and rear on a safe, flat surface, keeping your whole body and several consecutive strides in view.
   2. Gather the footage details, your usual pace and distance, the surface, shoes, recent training changes and any pain or other symptoms.
   3. Open a chatbot that can accept the footage, paste the supplied prompt and attach the clearest clips, stating which view each clip shows.
   4. Read the response and mark each statement as either directly visible in the footage or an interpretation based on it.
   5. Replay the clips beside the suggested cues and test only one comfortable change at an easy pace, stopping if symptoms appear or worsen.
   6. For persistent pain, a suspected injury, or symptoms that are urgent or worrying, stop the form experiment and contact a GP, physiotherapist or NHS 111 as appropriate.

   Prompt

   Analyse my running form from the attached footage. If you cannot directly inspect the footage, say so and do not pretend that you have. Describe only observable features, including posture, head and trunk position, arm movement, hip and knee movement, foot strike as far as the footage permits, cadence clues and left-right differences. Separate observations from interpretations. For each possible issue, explain what in the footage supports it, how uncertain it is, and give no diagnosis. Suggest no more than three low-risk technique cues or drills, with a simple way to test one change at a time. Do not tell me to run through pain. If I mention severe, sudden or worrying symptoms, tell me to stop and seek appropriate medical help, including NHS 111 for urgent or worrying symptoms. Ask for missing information before making strong claims. My context is: [age range, running experience, usual pace, distance, terrain, footwear, recent training change, symptoms if any]. The footage shows: [side view, front view or rear view, surface, pace and whether I am running naturally].
