He says he’s 81 - 82 kgs in response to this question on his Twitter feed.
One thing to remember is that Seiler is time crunched. He’s not an elite training 20 hours per week.
Looks like there is hope for me after all ![]()
Seiler is definitely mixing it up. He mentioned he does some (a lot?) zwift racing as well. A couple weeks ago he featured the Mat Hayman Paris Roubaix workout on his youtube channel…in true Stanimal fashion he did this workout 3x in one week & failed the first two.
So he seems to be doing some things that would be a departure from a true 80:20 prescription…but I think right from the get go Dr Seiler offered 80:20 more as an observation than a prescription, anyhow.
It’s interesting to note that his TTE ~FTP is way better than mine. On the other hand, when I tried the May Hayman Paris Roubaix workout I was able to comfortably bang out 50% more work than he was. Bet he would get better at stochastic workouts FAST if he threw them in the mix.
It’s weird that you’ve only done one block because I feel like I’ve heard about it over 1,000 times.
Cool beans, dude!
Now you’ve heard it 1,001. ![]()
This is my favorite workout

But also see Hawk’s Bill (+n), Mitchell (+n), Pierce (+n), Tecumseh, etc…
Fun, fun, fun…
Neither base nor race prep. I just had a lot of time during 2020 so I thought I’d experiment. I didn’t quite do it 100% bang on, I should have done more hard days and harder hard days.
If I get the same gift of time this year (which might be the case), I’ll do another round of POL, but much differently. First time was organized by session, next time I’ll do it by time and I won’t separate the sessions (as much). I’ll do more long “easy” rides with hard efforts thrown in.
I can guarantee that doing a 5hr Z1 (Seiler) ride with 10x30/30s @ 120% every hour* is going to be much harder than doing a 5hr Z1 on Day 1 and a 5x 10x30/30 on Day 2. Maybe.
*(or a 5hr ride with a 20min max effort at the end!)
I didn’t.
I used RPE, breathing, HR, and power for the “easy” days.
Would you mind sharing your plan? I’m currently trying to cobble up a plan by modifying TBMV. The plan was to add a z3 workout to the plan, but I’ve just noticed that the TBMV2 and TBMV3 start adding more time in zones 2 and 3.
Keep your easy days easy and your hard days hard.
You can have a hard day in z3… you just have to do 3-4 hours of straight tempo
Re: LT1 one estimate is 50 - 55% of power at VO2Max.
I been researching this in the last week and haven’t really found a method of estimating it that seems it might ball park it, well, that I’d be happy with anyway. All the ways of estimating it always seems to have a disclaimer it is very individual.
A well known coach had me training polarised for 6 months, his easy days were 2 hours weekdays, (but as long as you can, 4 if possible) - 4 to 5 hours the weekend ~65% of FTP. I assume this was to not exceed LT1. Had me do a threshold or high SST session about once every 6 - 7 weeks.
And how hard days look like?
Quick answer is nothing was ever under 105% of FTP (edit 102%)
I’ll have a look and come back on that to check my memory isn’t incorrect if there was something other then the normal ones you would expect
Lots of micro intervals, they seemed to be a favourite.
First was…
Supra-Threshold: 1H30M - 4x 8M 30S/30S Microbursts
which is 4x 8 Minutes (30S @ 125% FTP/30S @ 50% FTP)
and classics,
6x 5 minutes ~ 112 - 120%
Supra-Threshold: 2H - 6x 6M (rbi 4M)
VO2Max: 1H50 - 6x 3M 112% with Hard Start Intervals 135%
And how did that workout for you?
Speaking of LT1, anyone else listen to FLO podcast episode 50 with Sebastian Weber?
I thought it was a good interview overall, and he talks a bit about LT1 and LT2 in there.
Extremely well.
Ended up with a FTP within 5 watts off my all time high (5 - 6 years earlier.) Never felt burnt out or even close to being burnt out, could just live my normal life. By contrast when following a Threshold / SST model I was always on the edge of burnout or tired and somedays to tired to do those jobs around the house orwhen spending time with the family I was knackered and not really there enjoying the moment.
POL also resulted in a deeper fitness more resilience, could ride at a higher percentage of FTP for an age, SST fitness although a FTP only 5 - 10 watts lower seemed more brittle.
Note my all time FTP was all riding outside, training was just easy enjoyable rides (although most had hard moments) and hammer fests the weekend and once on week days, no idea what modality it was, didn’t know about modalities back then, but I’d guess it was polarised or HIIT
Thanks for sharing your experiences … your references to POL are all in the past tense - are you still following that style now? (with or without a coach)
No, its the middle of winter in the UK and we are in lock down so I don’t have the motivation to do POL 100% indoors.
For me its more of a way to train in, a ‘normal,’ summertime, those nice long easy outdoors rides in the sun.
Edit: Just looked this season up, since the 5th October, start of my season my weekly distribution has been… weeks that come out Pyramidal ‘Base’ 35% and ‘Pyramidal’ 60% and a couple of weeks came out Threshold edit 2 after feedback below also Pyramidal so 100% Pyramidal with slightly different mixes.



Right, that’s what I’m about to try for myself (also in UK, and missing the CX season). I’m starting by seeing if I can do a recovery week of Z2 stuff on Zwift to make the time go by faster. Am hoping to get outside instead in early mornings as soon as the clocks go forwards.
