What is it about riding on trainer that seems so much different that IRL riding? I have ridden about 5K miles on Zwift (and many, many more trainer miles in my life) and it just seems that IRL riding gives me much better conditioning than on the trainer.
98% of my time on Zwift is racing, and it is very intense, but it really doesn’t seem to translate directly to on the road fitness and strength as I always expect, especially given the intensity of the Zwift races. I suspect it is the static position and lack of other muscle engagement may be part of it. It also may be that Zwift promotes “grind it out” total power output instead of snappy interval type riding (like in many races and road training.)
Does anyone else experience this?
