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

How to improve your running economy + Owain's ACP 100K recap
(00:00) Intro(03:30) Anglo Celtic Plate recap(38:30) Economy discussionWe've done deep-dives into VO2max and thresholds, but here we cover the final final determinant of performance, running economy. First, we define what economy means and how do we measure it, before discussing what the research has to say on how best to improve it.The Physiology of Endurance Running podcast is proudly sponsored by SOAR.

Periodization... or performance planning
A common theme in training books is "periodization"... distinct focusses of training across a 12-week marathon block. But what does research say about periodization, and how is it implemented in elite athletes? Could you plan your training better?Dan & Owain talk about periodization, and the concept of "performance planning" on this week's episode.The Physiology of Endurance Running podcast is proudly sponsored by SOAR.
