Peloton Bike to iPhone/Health/Fitness sync: Duration incorrect

Hi SnickZ -

Thanks for the reply, I appreciate it but it doesn't really help.

I've already been updated to all the newest iOS and WatchOS versions, as well as all the requisite app versions. Booted and rebooted many times. Look at the metadata of the workout I posted - which clearly indicates a start time of 4:30 pm, an end time of 5:15 pm, and a duration of 45 minutes. That is what was sent over to Apple Health. The Indoor Cycle workout itself shows in Fitness and Health as a 45 minute workout, but the Exercise ring only moves to 38 minutes.

THAT is the problem; it's not the Bike, it's not the Peloton app - the issue is with the transmission of the output workout data from the Peloton app to Apple Health (which works correctly) and its population of the Exercise ring in Fitness and Apple Watch (which does NOT work correctly).

At this stage I'm just making inquiry to see if anyone else in these Communities has experienced such an issue or is aware of it. As I stated, I'm concurrently making the same inquiries at Peloton, but because the failure point in the process is getting Apple Fitness rings credit, it appears the issue is with Apple.

I had a long and interesting conversation with a senior engineer in Apple's Health and Fitness division yesterday, and I wanted to share what I learned with the Community. I think this might be a partial explanation for the behavior I've described.

The tech said that she *was* aware of some exercise routines -- Workouts generated by the Apple Watch, third party apps that shared data (like Peloton) and others -- that will carry a duration of XX minutes, but will only move the Exercise Ring by a different and shorter duration.

She said that the Exercise Ring moves not just in line with the duration of the registered workout, but with the "quality" (her term) of the workout.

She seemed to imply that, if in a 45 minute workout I was sitting still for 7 minutes, Apple Health might read that as only a 38 min workout in the Exercise Ring, even though it shows up as a 45 minute completed workout.

She further said that the only Apple Watch Workout "type" that always registers exactly the same time in the Exercise Ring as Workout duration is the "Other" workout type. (Peloton's workouts are registered as "Indoor Cycle").

Lastly, she said that the algorithm and methodology that the Exercise Ring employs to determine which activities are "Ring-Worthy" is confidential and a trade secret, and are not disclosed outside the Health engineering department (!!!!).

I pushed back on her a bit, saying that I have done slow 3 minute indoor walks around my living room that moved the Exercise Ring by 3 minutes, and that all Peloton workouts I did on my old (non-P) bike registered the time exactly in the Exercise Ring.

Frankly, the explanation sounded a bit far-fetched. And she agreed with me! But it is an issue she had seen before, and had some experience working with end users on the same problem.

For now, I will continue using the Peloton app as a "bridge" to Apple Health, but I may experiment with using my Apple Watch to manually measure an Indoor Biking Workout and to not use the heart rate strap with my Bike - and to switch OFF all of the read/write connections between the Peloton app and Apple Health.

Anyway - I wanted to pass along this interesting bit of information on this case. As I had guessed, the problem is on Apple's side, not Peloton's.
