This is a concept I began thinking about a few years. Since that time it developed into a usable tool. This post was sparked by Aidan asking if I find the MAF test correlates well with race performance. It is all related to the way I train and what I use as a guide to progression. To explain the endurance threshold, it is how far you can go at a certain pace until there is a significant increase in effort/intensity to be able to maintain that pace. The pace can usually be maintained beyond this point, but it is obviously much harder to do so. Joe Friel has referred to this as decoupling . His explanation is worth a read, plus the adaption for running on Ultrarunning . For me, I believe I use the concept slightly differently, and without all the extra in-depth analysis that he seems to take it. Basically it comes back to developing enough stamina to maintain the appropriate pace for the distance required. A personal example of establishing my endurance threshold was my marathon p...
