How so?
Can you point me to this?
I want a number to compare myself with everyone.
My whole worth is based on these pretend numbers!
No, I mean adding a TR VO2Max session in a week where I have some running amusement as well.
Im still unclear what youre trying to do, sorry.
The reason that you dont need to know the TSS for a run session when planning your cycling is that running does not cause the same kind if stress on your body as cycling.
1 TSS bike does not equal 1 TSS run, you should not be saying I want a total TSS of 200 so Im going to do 150 on the bike and 50 running, or change your mind and do 100 running and 100 biking.
They are oranges and apples, (and swimming are bananas) 
Sure there is only so much fruit you can eat, but eating two oranges is not the same as eating any amount of apples.

It doesnt exist. People want to measure all training in the same way so they force all sports to be recorded as “TSS” but thats just a convenient fantasy.
As for comparing with other people…thats what race day is for

Its always a tricky conversation, but this is a quote from the man who created FTP and TSS:
“Because there is no guarantee that 1 TSS = 1 rTSS = 1 sTSS. In fact, being developed by different individuals for different sports using different logic, they are almost certainly not equal. “
And;
“For over a decade I have been recommending that triathletes utilize Foster’s session RPE method (PPP: “If it feels hard, it is hard.”)”

Now that I have a few results (rTSS calculated by TrainingPeaks, TR-calculated TSS for TR workouts), I do think the TP rTSS numbers don’t really work. Case in point: Tallac yesterday. 60 mins total, 3x15min sweet-spot. 74 TSS, which makes total sense time- and intensity-wise. Today: 60 mins easy pace run, 75% max HR throughout, a set of 15-second strides at the end, nothing as demanding as Tallac was yesterday. rTSS from TP: 75. Duh?
I use SportTracks, which has a TRIMP model for effort/recovery tracking. For Tallac, it calculates an effort of 99 (I don’t know 99 “what”, but anyway), and the ratio of TRIMP-effort to TR TSS for TR workouts is constant. SportTracks calculates an effort of 37 for my easy run, which would translate to 28 TSS if that same ratio applied. The TRIMP model sees my easy run as less than half the effort of Tallac. TrainingPeaks sees it as the same. It sure didn’t feel the same.
So back to the drawing board.

I am with you on this.
TR wo this AM was a 1 hr run.
WU and 8 x 1’ at “All Out” (RPE10) with 3’ of Easy (RPE2), follow by cd
My Wu was about 8:25 pace (hr < 145)
Each rep was about 5:25 pace (hr on last one was 190)
Rest got way slower after every rep (from 8:30 to 9:10 on the last one)
cd was slow at 9:10 (hr ~168, hard to low the HR when the temperature is about 1 billion degrees and humidity is about 5 billion %)
TR thinks that should be a 90 TSS effort.
TP said it was a 71 effort
Strava had me at a TRIM of 119
Elevate has me at 71 HRSS
So which one to belive? I have no clue.
My main issue with ANY of them. They do not take into consideration Altitude or weather (wind and temperature primarily).
When you are deal with bike power, thats something that you can measure. When running there are so many variables that you would need a ton of sensors to measure it right.

I’d think that given a flat road and negligible wind, running pace is a pretty good analogue to power, at least for a given individual. That’s why JD plans work, by the way: they are pretty similar to typical power-based cycling plans, and you can’t cheat an interval set based on pace, just like you can’t cheat an interval set based on power.
In any case - it’s all good. TR takes care of offering me a cycling plan with a reasonable effort ramp, and JD takes care of offering me a running plan with a reasonable effort ramp, so the sum of both should be a reasonable ramp.
This said - aren’t high-intensity running intervals something?
This said - my max HR being just shy of 160, I see your numbers and imagine an ambulance.
OH yeah! I ve done high intensity training like this for years, but its been just running. Man once you add cycling and running into the mix, its a whole different ball game.
Ha. Yeah. I get that a lot when people see my HR. I actually can go as high as 201 (i seen this only a few times tho, but when i see it, my hands get tingly. Its a very weird feeling). Usually on 5k it goes to 195 at the last half mile.
Sure. You also must take into consideration wind.
JD doesn’t take into consideration heat. Or at least not on his suggested training paces.
He can give you equivalent of race pace after a race in the heat. But doesnt give you alternate paces when its too hot. Right now in FL the TDP is above the recommended for doing exerciser outdoors, and i was doing a somewhat heavy training at 7:30 am, with full sun.
I love JD plans. And i would do them. But if you try to follow him, with TR, you might very easily over-train.
I don’t know that rTSS is supposed to be a comparable value to a bike workout. Running stresses your body differently (obviously the pounding your joints take). There is absolutely no way I could handle the amount of Bike TSS if I tried to replicate that running. My body would break down. Similarly, when I was doing tri’s, my CTL was significantly higher (around 150 leading up to a full IM) and I could never replicate that just on the bike.
Hence the reason that they call it rTSS vs. just TSS. While the default CTL number on the homepage is an average of all TSS recorded, you can (and should) track TSS in your individual sports in the Performance Management Charts
As I said elsewhere, I stretch both over time. I’m doing LV TR plans at 2/week (so it takes me 3 weeks to do 2 plan weeks), and JD at 3-4/week (so it takes me a bit more than a week to do my 4/week plan). Overall, that’s 5-6 days/week, not counting maybe an easy bike ride during the weekend - sustainable, as far as my knee tells me. It’s the first time I ride both plans in parallel, so still some trial and error.

The way TP appear to calculate rTSS, I can easily handle the same level as bike TSS… but if I tried to bring my running to the same cumulative effort as a 3-4times/week TR program as calculated by SportTrack’s TRIMP model, that would be another question altogether.
For sure. And it also depend on the person. I am weak sauce. So mixing JD and TR didnt work for me.
Well, I like to blame the Florida heat. Is hard to recover when everyday is so hot.
Have i say i hate training in FL?
Come here, we freeze.
Did I say I do not run in snow and slush? I refuse to do so?

I rather run in 0 degrees than 90 and 100% humidity any day.
If is cold you can always layer up
If its hot, there is only so much you can take off before you get to jail. And even then is probably not enough. 
Running 1 min intervals at 5:25 (per mile, I presume)? Right.
yes miles.
And fair. But i personally cant keep that level of effort while also doing hard bike wo.
This AM i was going 100% capacity and wishing for a quick death at the end of each interval.
An example. At this point in JD (about 5 weeks into the 10k plan) I would probably be doing 400s and 800s and starting to add a few consecutive miles at T pace. If i attempt a T pace wo, i wouldn’t be able to do a threshold or SP bike ride the next day. Already tried. Already failed!
like i said…weak sauce. I do, however, have a good kick. So i can knock out few short rounds like this and make it sound like im fast… but i am not.

Oh, no…fook that. While I have run down into the single digits, it is miserable. Give me heat & humidity any day. Some of my best tri’s were on oppresiver days when everyone else just wilted. Same with my PR for a half-marathon. When we started at 6:30 (I think) it was already 80* and humid in downtown Chicago. Finished looking like I had jumped in a pool (seriously…literally dripping wet), but still PR’d.

Its funny how different people run in different weather.
I crumble with heat. I suspect it has to do with the objectively high HR i got. but i dont know. I tend to do better in the cold.
I know a woman who has shown that she actually perform better in the heat. I am not like that, but opposite!
I grew up in hot & humid conditions…DC, Florida, etc. I don’t know if there is such a thing as long-term acclimatization, but for whatever reason, I still perform well in it. And usually the longer the better…
