Counterpoint to FTP obsession

[rswagler1]

The FTP/durability discussion came up last year, when Andy Coggan was still posting on the forum…

How do you train the Durability?

I believe that one reason* many view these as separate abilities when they really aren’t is because of the shallow slope of the exercise intensity-duration relationship. It’s a lot easier to detect, say, a 15% increase in time-to-failure than a 2% (<5 W for many people) increase in FTP, even though they are exactly the same thing. *Of course, the A#1 reason is overestimation of FTP due to 1) use of suboptimal tests, and 2) ego.
