Trainerroad

some software (Training Peaks for example) will offer hrTSS, which I find to be reasonably close to power based TSS (assuming you have set your functional HR correctly) for longer rides that are fairly consistent efforts - it will typically under read any high intensity short efforts however.

I only have Strava and Trainer road...
It doesnt need to be that accurate but enough to monitor load.

There's probably some modeling out there already, like
https://www.cyclingforums.com/threads/trimps-to-tss.407676/

I generally estimate based on previous rides of similar duration/intensity if I don't have powermeter. RPE and duration and have a think about what was similar in the past. Depends if you have a decent back catalog of TSS though, of course.

Chrome Elevate extension gives you HRSS

Looks like the easiest solution. So just add the calculated stress score to my TR activity from strava?

hmm taking a closer look, you'd still have to take with a pinch of salt.
Had my HR zones done with lactate testing a year ago yet my HRSS is often well below my Power based Stress Score - about 30% lower. This may vary with other people.

Anyone else running their KICKR a bit higher or lower than their PM watts?

I treat them as separate devices. Like if I had an SRM and a Quark. All my turbo training is based on the Kickr, outdoor is vectors.

But in general, I do my ramp tests with both. Vectors read higher at low power, but lower up at the sharp end.

How does this work in terms of your head unit? Which do you show and how can you compare afterwards? Two head units?

I only use PMs normally but don't have a PM on the KICKR at the moment so want to know if it generally reads a little high, a little low or about the same as a PM.

I’ll try to find the last 2 ramp tests so you can compare. But, mine is not the newest kickr.

TrainerRoad for the kickr - wahoo for the vectors as a reference. Outdoor (vector) power is different anyway although I’ve tried to do some vo2 max intervals outside recently.

But @hippy - just do a ramp test!

I'm not trying to work out my FTP I'm doing set power intervals but I want to know if I set 450W on the KICKR what will it be when measured at the Powertap? I train off PM data, adjusting the load on the Computrainer/KICKR to get the PM where I want it. But currently I don't have a PM on the KICKR bike so I'm trying to make sure 450W load = 450W as it would be measured at the PM, if you get me?

But I'm going to do a Ramp Test at some point, just to see what number it spits out. I just don't have any days where I'm fresh enough to bother at the moment.

+6% on my FTP through ramp test this morning compared to beginning of the year and with 2kg lost (70kg), wanted +10% but happy with that I think

Good work!

Does TrainerRoad supply outdoor versions of their workouts now? I'd quite like to give it a go, but I'm trying to avoid indoor bicycle riding as much as possible. Has anyone got a free trial going spare?

They do for Garmins. Wahoo is in the pipeline too apparently. PM me your email address and I’ll send you a trial.

PMed. Suppose it's always an option to rebuild the workouts anyway.
