HR+ set power ceiling

Alex,

You’ve set up a power floor for HR+, but not a ceiling. What do you think of allowing users to set a “do not exceed” % of FTP for HR+ workouts as a ceiling similar to what is offered for the floor currently?

The idea is the algorithm controls, but does not allow commanded power to exceed the set percentage.

For example, let’s say I choose a max % of FTP for HR+ to be 75%. I set up a workout with a heart rate of 130 BPM. Let’s say during the workout my HR is only 115 BPM and power is at 75%. The algorithm will not increase power and will control to the best of its ability given this constraint.

Why offer this? Every time I try to use this feature power goes high at the beginning and often into tempo power as HR takes a relatively long time to go up and is not consistent from workout to workout. I can tell a difference in perceived fatigue from workouts that go into tempo for a period and those that do not.

I have an idea up my sleeve to try and work around this issue, but is manual.

For users who didn’t want to use this feature it could default to effectively infinite power.

Edit, I misunderstood. Yes we have power floor but not power ceiling. We attempt HR ceiling. Let me think about this. I understand what you are looking for and agree with the idea/problem. You ultimately want even slower increases is another way to look at it. For now you can do ERG warmup will solve the problem. Unless it happens during the workout too.

The more I think about this I think the slow raise power solves your problem and saves me a lot of support time or users forgetting/frustrated… If you set a power celling for your current desired limit one time in settings, and in the future you forget and want to do a tempo HR+ workout and it does not work and you forget why…. I think just having an option to increase power slower but allow dropping at the same rate would likely solve your problem (and others) in that their heart responds more slowly. Does this make sense? The other option is use the ERG target in the workout as a celling with a setting to use power target as celling but I still think people will forget and if they just wan to hop on quick start and set target it does not help.

Sure, I just wanted to pitch a suggestion.

I tried my workaround yesterday and it does work, 5 minute warm up then control at a low heart rate (I tried 115 BPM). Increase HR as you get farther into the workout and you notice power starts to come down.

I’m not opposed to power based workouts either, but people have had a lot of success with HR+.
