My KICKR is relatively new and have only ridden a couple hundred miles on it exploring Watopia, N.Y., London, and other locations. Did most of Alpe de Zwift and a few lesser climbs while trying the rides. I usually ride around 200W with a few jumps up to 300. Have an OK fan and sweat like a pig but keep my water intake up. After an hour, I am whipped. Always a good indicator of how tired my legs are, are the last two steps going up to the second story. I can ride outdoors for two hours at 18 MPH ave speed and usually climb 2000’ but the trainer just wipes me out. I know there is little coasting ‘recovery’ on the trainer but am wondering if the mileage, speed, climbing % on the trainer are so far from reality that they should just be ignored or used only for that bubble/world?

On the plus side, on Strava I am starting to knock off the guys in my age bracket on lots of segments getting fastest time.
