I was hoping you could help me with some information related to how CTL is calculated based on either hrTSS (heart rate) and rTSS (running), and tTss. What I have found is when I log running workouts on my GPS watch and upload them to training peaks they will generate different TSS scores for the same distance, duration, and elevation gain during a run.
Example: I run for 60 minutes on a treadmill and log 6 miles with 0 elevation gain/loss. It will log the score as hrTss and give a score of say 43. If I run outside for 60 minutes and log the same 6 miles with no elevation gain/loss it will log the score as rTSS and give a higher score of say 63-67.
My question is, should I be using a “fudge factor” for the runs I do inside when they are calcuated in hrTss? I realize that TSS, CTL, etc. are crude measures. Still, it may be because I’m OCD, but I try and keep the logs as accurate as possible because I monitor the ramp rates and compare that to how my body feels to ensure I don’t over train.
If anyone could shed some light on this situation I’d very much appreciate it.
