Training data reveals injury patterns weeks before runners get hurt

A study of 643 marathoners shows that wearable metrics and training logs can identify biomechanical and physiological warning signs 2-4 weeks before acute injuries occur. If the finding holds at scale, injury prediction becomes a real use case for fitness wearables—moving them from post-hoc tracking to prevention that insurers and team sports might fund. Running injuries currently sideline millions annually with minimal prevention, so a validated predictive model would shift the industry's value proposition from consumer gadgetry to defensible clinical utility.
