A great conversation between the fascinating Dr Alex Hutchinson and sports physiotherapist Chris Napier. Alex Hutchinson will be known to many because of his sports writing for Runners World (in the past) and Outside Magazine (now). He spent 9 years asking the question that is the title of this podcast – you get the answers in 20 minutes!

In addition to the discussion of limits of performance, they share practical tips on how to improve your own running times!
