SPLT.400 Pro provides modelling, pacing analysis and coaching insight based on historical 400m race data and user-entered split information.
No medical or injury advice
The app does not provide medical advice, injury diagnosis, treatment advice, rehabilitation advice or health screening. Athletes with injury, illness, pain, symptoms or medical concerns should consult an appropriately qualified professional.
No guaranteed performance
Outputs should not be interpreted as a guarantee of future performance, competition results, qualification, selection or improvement.
Model range
The current model range is approximately 43–73 seconds for 400m. The usefulness of the model is strongest where sufficient comparable race data exists. As more race data is added, coverage and accuracy can broaden and improve.
Use of Coach Insight
Coach Insight is an interpretation of the data entered and the matched race model. It should be used alongside coaching judgement, athlete feedback, race context, health status, training history and environmental conditions.
