I think the micro-accelerations are even less when riding fast on the road.
IME, fast road vs steep climb are on opposite ends of the spectrum of ride feel. I do a lot of steep climbs. Not so much fast road. So fast road riding for me feels a lot harder vs climbing.
When Iād hear Lance Armstrong talking about cross tail winds being the hardest conditions to ride in, it took me a while to figure out why. This article does a nice job explaining.
Only just about everybody, I bet! 
One thing I found outā¦when I turned into a headwind the first thing Iād do is get aero. Then Iād pedal along at the same power. Once I got on TR Coach Chadās Evil Texting Imp taught me that I canāt ride in an aero posān at the same power as I can while sitting up on the hoods.
That was the biggest thing for me. Same power in the aero posān is a bigger effort.
On the other hand I hate working hard in a headwind on a hot day then absolutely roasting after the turnaround. One nice thing about a headwind is that it does keep you cooler.
This turned out to be pretty interesting. I like this micro-acceleration resistance idea a lot. Think if you add that to the cauldron weāre pretty close to the suck factor equation.
Would be interesting to see it tested, a rider all strapped up with sensors etc
@Joelrivera thatās just bbarreraās smokescreen for those rare rides when he actually doesnāt get a KOM or PR.
You guys arenāt going to goad me into updating my unintentional KOM near the interval start. Unless some bozo steals it today now that itās been converted from Sector 1 Pave into smooth tarmac 
Donāt feel bad about getting a KOM in a tailwind sometimes. Unless youāre the guy I have driving around town with his TT bike in the trunk to take my KOMs but only when winds are 15+mph in his favor
I usually never chase CR.
But if winds are favorable and they are near my house I will tryā¦
Was looking at a KOM today, clicked the guys rideā¦ average speed 24.5mph on a 110 mile loop!
I was like wow fast dude, was expecting the KOM to be a mad tailwind, but he has KOMs all over the loop.
Then I saw the commentsā¦ he was motorpacing!
And quite proud of it too.
The TT guys thoughā¦ fair play to them. We just canāt compete. If you get a crazy TTāer who can handle strong tailwinds they will blow everything apart. Iām not experienced on a TT bike and have had to sell mine last year as I had no time - but I was always nervy on it. Much respect to guys who can hold TT position in winds many roadies are scared ofā¦
We should all be in different ride types I think, but not enough TTāers for them to buy into it.
Thatās a perfect candidate to flag and report to strava. Look up Joe Lawhorn #593 on Strava
he does some legit amazing TT rides without a car
Yea and since maybe Iām derailing the thread a bit, Iāll say he definitely rides into headwinds as he is outdoors every day no matter what the conditions are, blizzards included. Those Marines are tough
Back on topicā¦
A lot of speculation on reasons, some sound like excuses and only a few are actionable. Here is what I propose:
Try that on a couple of rides and see if it makes a difference on ability to put out power.
Thats not the same position as when climbing, because of the weight shift due to the bike being on a gradient.
Donāt argue minor details, the point is to replicate the body position as much as possible. Iām not some freak just because I can put out the same smooth power on flats or climbs, at 90rpm or 45rpm, headwind or tailwind. Its a skill and there is a mental component.
No, I think the body position difference is important, as is the inertia/torque component. I do think the magnitude of it is individual, it would have to do with body mechanics, for example leg length or shift in centre of gravity. For some people, it might come natural, but for others, it definitvely does not. Just look at the replies in this thread. I do agree that there is probably a skill to it, and what exactly that is was part of the reason I started this thread. Nobody is denying that there is a mental component, but we all know that and itās not of interest to me.
Saying āitās not of interest to meā sounds like you are giving the mental component a pass 
We have windy Strava segments affectionately named #strugcity and Gale Force Sprint for a reason - the wind is howling and you can barely hear anything, you are putting out threshold power, the gusts will make you go well over threshold in an effort to keep speed constant, riding in an echelon is a struggle for survival, your speed is 13-15mph solo instead of 20-24mph, the out-of-area guys/gals are mentally giving up and dropping off the back, etc., etc.
So I have a few questions after re-scanning your posts:
Your local āclimbs last a few minutesā and you can āride into the wind for hoursā - should I take what you wrote literally and you are comparing a few minutes climbing to riding in to the wind for hours?
In the original post, you mentioned keeping the same position (eg in a TT) the headwind feels harder but in the preceding sentence you said climbs you open up more and headwind you get more aero. Have you ever tried mimicking a climbing position (e.g. hands on bars) while battling a headwind for a couple of minutes and confirm you can put out the same power?
Any data on HR?
Sorry if Iām misinterpreting your posts, however my original skimming of your posts led me to believe you are:
and then trying to compare two dissimilar efforts.
Personally Iāve found 1 hour climbs and 1 hour headwind rides to be more similar than different. On those hard 85-95% FTP efforts, Iāve never noticed āmuscle activationā to be an issue, instead it has always come down to muscular endurance (strength endurance). Iām often undergeared on climbs, and so I practice that on the flats into a headwind.
Now punchy 1-3 minute climbs are a different matter, thats all about being able to go way above FTP which is something I practice on the flats (1-3 minute over FTP intervals) and those transfer nicely to short punchy climbs.
I was just trying to have a debate on the physics of riding into a headwindā¦
I think this is really a personal thing. You are one of those people who donāt lose power into a headwind, others (like splash and myself) do.
And no, itās not because a 30min headwind section is longer than a 3min climb (surprise ), and no, itās not because Iām ashamed of going āslowā, and no itās not because Iām not used to riding in a CdA <0.18 position.
I do find it interesting how much the effect is different for people and what the potential reasons might be (biomechanics, breathing). Fwiw I also lose a lot of power on the turbo.
Iām going to try replicating a more climbing position this week into strong headwinds, and mentally tell myself Iām on a climb. Actually treat it like one. Physically canāt totally match or activate the same muscles of course, but might be able to undo one element of the suck factorā¦ worth a try, not doing much else other than being blown around for hours anyway!
