Why would a Family Doc be researching Running Techniques in his spare time?

I have been a runner since age 13 and ran competitively at University of Virginia in the mid 80’s. My interest in medicine was sparked after experiencing our team physician Dr. Danial Kulund of Charlottesville try some seemingly bazaar at the time and innovative approaches to running injuries.
He was the first to have people run in the pool and built orthotics in his toaster oven. It seemed like there must be better ways to treat these maladies and Dr. Kulund blazed his own path. Oft injured Mary Decker Slaney was one of the first of Dr. Kulund’s patients to have running rebirth by his methods.
