Firstly, two important notes:
- (Easy) TRIMP is independ not your VO2max. ATL/CTL/TSB/Easy TRIMP are all based on your trimp values and they are based on heart rate und duration only. In terms of TRIMP, a 1-hour easy run is always the same, no matter what's your 'easy' pace.
- The Easy TRIMP is just a calculation to reach a TSB of 0 which simply means to stay at the current load level. You probably don't want that every single day.
I personally don't look at Easy TRIMP at all. I usually don't put two hard days next to each other and try to get not too low (or too high) values for TSB - or, even simpler: try to keep A:C within 0.8 - 1.3. But all of that is independent of my current VO2max.
Athletes with a high overall load - which implies high Easy TRIMP values - can still have complete rest days (and get a TSB somewhere at +20 afterwards) and will have hard days ending at a TSB of -20. That's fine.
Thanks for the details and clarifications!
I probably mis-spoke as I'm not super edified on the technical terms (although I did read on them), so at least for my running journey, at the beginning even a slow jog at 6:30 mins/km pace my HR would go into the "red" zone. These runs at low VO2max/high HR generated a lot of TRIMP. But after 2 years I don't really even run at that pace anymore and even though I increased my mileage (from around 50km/week to about 92 the last month) and pace, the HR generally stays low enough to generate much smaller amounts of TRIMP.
One other interesting "phenomenon" I noticed was on the Calculations/Show Shape graph. Let's say in December last year, I am fairly sure that Fitness CTL and Fatigue were quite high. What were once 100% Fitness, is now 6 months later/with some progress just 80%.
Workload ratio seems to hover around the 0.95 area on a usual day, after my run. I'll listen to your advice and keep that figure more in mind instead, thanks again!
