Just one more clarification please
regarding zone 2, is it the best to use the heart rate based or maybe FTP based?
the pure zone 2 is derived from the lactate level (based on the podcast i copying below), ofc i do not have ways to assess this.
Any thoughts on this?
55-75% of FTP if you have a power meter. Though I also find RPE is a very good gauge for z2 training, everybody who has spent time training for endurance sports has evolved a pretty good feel for that intensity which isn’t easy, but feels like it can be sustained indefinitely.
