The original FatMax work comes from Achten and Jeukendrup (Fatmax: A New Concept to Optimize Fat Oxidation During Exercise?
Eur J of Sport Sci 2001. https://www.researchgate.net/...tion_during_exercise)

Here are references from Jeukendrup himself:

http://www.mysportscience.com/...our-fat-burning-zone

Whatever the FatMax intensity is (and as you can see above, it's not super easy to determine it
without some metabolic testing), my original question was: what are typical training sessions
at this intensity?

Continuous ride for X hours, intervals?
