Running Injury-Free uses anecdotal examples from Ellis' own patients and experiences in order to discuss injury-prevention, treatment, and recovery. He implements a clinical approach toward treating the most common running-related injuries, as well as providing detailed background situations to describe how each injury can happen, so the reader can recognise poor habits or compare training and running practices in his or her own experience. In this updated version, content relating to shoes and shoe selection, "over the counter" treatments, orthotic techniques and materials, Piriformis Syndrome, chiropractic medicine and acupuncture, stretching techniques, nutrition and supplements, injuries related to minimalist runners, as well as running issues for women, children, and endurance runners will be updated to reflect timely practices and research.
