I think this explains Resistance Mode. That’s where I first know about it - BreakAway: Indoor Training App Now with Intervals.icu Calendar integration (Workout Of The Day) - #131 by app4g
This was how @SaSha1103 explained it to me initially.
in slope mode, you are using an outdoor ride and riding it indoors w/ all the different gradients similar / same as that of outdoor. (BTW - now you can control the trainer realism as well - BreakAway: Indoor Training App Now with Intervals.icu Calendar integration (Workout Of The Day) - #158 by app4g)
In Slope in Free Ride Mode - Basically, no graphic to follow the target power.
Currently this is already possible using ERG+SLOPE mode. (Slope Based Structured Workouts Now Supported (BreakAway: Indoor Training iOS)) but the downside is there is no graphic of the target power.
I will be adding this possibility later on.. (again as a hack - I’m thinking doing something like %%Slope 2%% to indicate this interval is using resistance)
right now, the semi solution is to define your workout, then use resistance mode and manually change it PER interval if needed.
