After doing the no-vid Cadence Builds/Holds/Single Leg Drills today, I am wondering if this is better done in erg or level mode.
The build/hold segments were not a problem, but I found that the power and cadence targets in the single-leg segments were confusing. In erg mode, the trainer (Wahoo Kickr) would keep me at the target power, but as the cadence got much above 50% of the target the resistance was so low that there was almost nothing to push against on the pedal downstroke and the overall stroke was uneven. If I switched to level mode I could get the cadence higher and smoother through choice of gear, but then the power was significantly above the target.
So the question boils down to what is the best approach to the single-leg drills, power or cadence and erg vs level mode.
