SMART intervals are comprised of two types.
Those that scale to your evolving fitness signature and are not anchored on %(F)TP. Example, MMP and %LTP options. Or dynamic intervals that vary in duration or power using XSSR and Target MPA options.
You are describing a dynamic power interval that changes target watts based upon compliance during the duration of the interval.
My suggestions would be –
- Use the new feature to export a selected workout to your Garmin unit. The icon
is shown as long as the workout includes less than 50 steps (Garmin limitation).
The workout will run as normal (%FTP targets) using Garmin’s outdoor format.
Yes, you lose SMART functionality, but the strain goal is the same and targets are based on your current signature. - Try creating a similar workout with dynamic duration intervals instead which will shorten or lengthen (up to 50%) based upon compliance to target. In this case a failure to attain the target would lengthen duration while overshooting would shorten it. The idea being once you reach the strain goal you’re done.
- Consider learning how to Free Ride to Focus to meet your strain goals for the day (Focus Duration, Difficulty, XSS). No need to load a workout onto your Garmin. Instead monitor a few Connect IQ fields (Focus, TTE/TTR, Difficulty, XSS) during the workout portion of your ride.
