I have a dumb trainer (cycleops fluid2) and I was thinking of using it as David mentioned above (speed as power meter).
Problem: at a sustained speed, this trainer is known for increasing resistance over time (maybe because it warms up).
Recently I’ve found a test with this trainer and a power meter.
The guy sustained 90rpm (with the same gear) and the output measured power went from ~245 to ~315 in just 8min!
So, in my case I’ll keep using heart rate zones..
By the way.. my biking LTHR is about 10bpms lower than my running LTHR.
