Thanks very much for this Reed. Makes a lot of sense that it is more individual rather than a set number.
My CTL is running around 55 at the moment. Think I could do level 2 of Chamonix Mountain Fit probably every day if I had the time but level 3 is a big step up. I’ve been plugging in a TSS of 40 for the workout, so similar to a Z1 40 minute run. This is probably an underestimate for CMF level 3 but I think I’ll stick with it for now.
It’s nice to plug in the numbers and see the CTL going up as a positive feedback loop and putting some sort of metric on it but I guess at the end the day it’s really about feeling better, achieving your aims and better form during the workout.
