I can hold X watts on TR (in my case X is a minuscule number but surely an awesome one in your case), I can hold those same X watts on the road in the calm or with a tailwind with nary a budge in the RPE needle. However as soon as I turn into the “Dutch Mountain” and face the wind it all gets creaky. That same X starts to nudge the RPE needle into the surrender zone. What gives? Is it purely in the head or is there something real there? Some sort of change in the force distribution in the pedal stroke? I have tried various psych out tricks over the years (ear plugs to eliminate the wind noise, reducing the computer data fields to power and cadence only, so I can’t see how sucky the speed or time are). Nothing seems to work.
I notice that some of my training buddies have it worse than me and die totally in the wind to the point where we go from me having been barely hanging onto their wheels, to them having to suck mine all the way home. Now I make a bigger hole in the wind than these guys so it is not that. When I ask them they come out with the same observation. So in the head or real?
