Rodger Kram PhD is a professor emeritus at the University of Colorado, Boulder. He is one of the most sought-after biomechanists of our generation having published nearly 200 peers. He is also a consultant to Nike and contributed greatly towards the Breaking2 project. Rodgers academic interests are in the biomechanics of human and terrestrial locomotion, including steep running, the effect of cushioning and carbon plated shoes, and human performance. Some of Rodgers recent work:How Biomechanical Improvements in Running Economy Could Break the 2-hour Marathon Barrier.https://pubmed.ncbi.nlm.nih.gov/28255937/A Comparison of the Energetic Cost of Running in Marathon Racing Shoes.https://pubmed.ncbi.nlm.nih.gov/29143929/ The Biomechanics of Competitive Male Runners in Three Marathon Racing Shoes: A Randomized Crossover Studyhttps://pubmed.ncbi.nlm.nih.gov/30460454/Uphill Treadmill: https://www.youtube.com/watch?v=N8DdJaXnZGgFollow Rodger on Twitter- @RodgerKramInformation on coaching- www.trainright.comKoop’s Social MediaTwitter/Instagram- @jasonkoop
