Here in the Dallas area, it is quite common to have wind speeds in excess of 30 mph with gusts up to 40 mph. Today was no exception. When I was out today during lunch doing threshold intervals with the wind at my back, I was doing over 30 mph at 100% FTP. My cadence was in the 97-100 RPM ballpark. This feels like a perfect cadence for me to do my threshold work. On my way back to the house, with the headwind, I was doing about 85-90 RPM. It hurt much more. I tried going to a lower gear to get the cadence higher, but I just couldn't generate 100% FTP at the higher cadences that I could with the wind at my back and at the faster speed.
This makes no sense to me at all. Is it just psychological? I was probably doing about 16 mph against that wind with an occasional dip to 12 mph (or slower) up the small inclines here and there.
Has anyone experienced this? I'm thinking it may just be psychological.
