I might scour TR’s library and see if I can find some. Carpathian Peak +2 is one of those 95-105% over-unders. Using Kickr 2017 direct drive with PowerMatch, the power looks nearly identical to going outside (or inside) and doing a threshold interval: > [@Am I wasting my time on TR?

Carpathian Peak +2 - does it vary between 95% and 105% FTP? I did it a couple years ago using TR app (Kickr direct-drive 2017, Erg, PowerMatch) and putting it on a 95-105% color grid: It looks similar to my outside rides at threshold. Have you ever done a long effort at threshold? Do you know your usual threshold HR? Mine varies a little by time of day (lower in morning), cadence, … For working on both race specificity and lactate clearance, my coach at FasCat assigns ‘criss-cross’ or ‘sweet spot with a knock’ intervals, which are variants of what Kurt is talking about and discussed here: > **[How to improve your lactate threshold as a cyclist — High North Performance](https://www.highnorth.co.uk/articles/lactate-threshold-cycling)** > > This post explains what the physiological mechanisms comprise the lactate threshold, how the balance of an athlete’s aerobic and anaerobic capacity influences where the threshold occurs in relation to the VO2max and presents a number of effective... as ‘Significantly Over/Longer Under’ and I have found them to be highly effective at pulling up ftp. And I completely agree with HighNorth’s comment just below the Steady State 2x20 at threshold interval example. --- _[View the full topic](https://www.trainerroad.com/forum/t/coggan-s-physiological-adaptation-chart/75468)._
