In this second episode of The Physiology of Endurance Running Podcast, we explore all aspects of the 2nd threshold. We cover:

What is the 2nd threshold and why is it important for performance
What do we know about the determinants of the 2nd threshold
Do we know how best to train it?
How can we use the critical speed model to calculate our 2nd threshold outside of a lab and without lactate measurements
How can we apply the critical speed model to our own training

Critical Speed Calculator

You can access the calculator via this link. You will need to download the Excel file in order to edit the document. Let me know if it doesn't work!
