1hr20, with 60mins at 231w (89%). felt great could have kept going for longer, really.
I don't know if anyone else gets annoyed when they have a power/cadence dialed in and the fluid resistance decreases on the trainer. I assume many fluid trainers have this to varying degrees, just a bit of a pain to have to spin a little too fast or too slow at times to stay at a desired target (plus I have 8 speed cassette so not a lot of fine tuning on that)
