Threshold Part 3 - Mathematical Thresholds

So far I've looked at the biochemistry behind thresholds, and evidence for whether thresholds exist (it appears they do, but not the one we all call 'threshold'!). For this post I'm going to look at some of the ways that we have tried to describe our thresholds and limits.

Combining Zwift with Sufferfest/PerfPro (or TrainerRoad)

Is it possible to get the best of all worlds?
