Force Garmin Edge to not set ERG mode to the avg of interval power?

[app4g]

@Gabriel_Vargas is correct, SLOPE/SIM mode is not supported (and not configurable) within Garmin Watches / Headunits.

Your best bet is to use a 3rd Party App.

BreakAway supports auto switching from ERG → SLOPE → ERG within a workout automatically (workouts Sync’ed directly from intervals.icu)

Slope Based Structured Workouts Now Supported (BreakAway: Indoor Training iOS)

For Slope of 2% (resistance mode) something like this would work - 10m ramp 40-60% (67-100w) - #2.0% SLOPE# 60m 80% (134w) - 10m ramp 60-40% (100-67w) The initial 10m + 10m (warmup / cooldown) will be based on ERG. the 60m will be at 2% Resistance/Slope, the 134w is just there for the workout graphic to show where you should be hitting. (modify it per your 115w = x% of FTP) [Screenshot 2023-09-08 at 11.47.21 AM]

I believe Auuki also supports SLOPE mode, however, you may need to physically change the modes.
