The Physiology of Endurance Running Podcast
Dan Nash and Owain Zerilli
This podcast is all about getting sport science research out into the public domain. We cover what we do and don't know regarding all topics related to endurance running performance and, more importantly, how can we use this information to make ourselves healthier and faster runners! Your hosts are Dr Dan Osborn-Nash, 2:12 marathon runner and sport physiologist for Welsh Athletics and Welsh Triathlon, and Owain Zerilli, MSc student exploring the effects of heat on EPO release and 2:38 marathon runner
