[request] Stop sending speed data to strava

It would be in Strava’s best interest if the distance shown from trainer rides was representative of the actual effort so as to maintain the legitimacy of their distance based challenges which accept indoor and outdoor rides. I could do a very easy endurance ride at 40% FTP on TR in the hardest gear so it may show me doing 60km/hr which would put me in an undeserved spot on the leaderboard since I get a long distance without much stress or time.

I also think these Strava challenges can make cyclists faster as it’s another form of training motivation.

We can agree to disagree. The only way for Strava to do this would be to build its own cycling physics model, and recalculate speed and distance for every virtual ride. And that still would have pretty big errors due to unknown/ inaccurate rider weight, rider CdA, etc.

Once you let virtual rides in, you accept that quantities like speed / distance lose meaning.

Strava calculates power and calorie estimates (if you don’t have a power meter) based on your weight and your speed data.

Zwift calculates your speed (more accurately than TR because the estimates are higher than TR :wink: )

I don’t think this is a problem the engineers at TR can’t solve.

I’d like to track “miles” on TR bc I track the wear and tear on my Kickr Bike. Ultimately, (and I realize I’m in the minority) I don’t care about the accuracy.

Does the kickr bike not have the option to report virtual speed (based on power) rather than flywheel speed?

The wahoo kickr and core trainers (and maybe the snap?) have this option and I think it’s a great solution to track realistic distance/speed while doing indoor rides.

This is obviously ignoring the can of worms which is deciding if virtual distance (what you want) or flywheel revolutions (what you have) is the best way to track kickr bike wear :wink:

Ironically, this whole debate may be settled when/if Zwift does indeed swallow TR. Assuming TR would adopt the Zwift physics engine that determines speed, or we’d just be forced to ride in Zwift’s virtual world.

I have no idea. I haven’t used the app since I configured the shifters and gears. It’s more of a novelty though - Strava allows you to tag your gear with each ride and it tracks your distance on those parts. It would be sorta nice to have a total distance in Strava as well as being able to break it down into how much on each bike. I mean I do that but I think the numbers I’m getting on the Kickr Bike are low for some reason.

Update on this. We’re a few weeks away from having a feature out where you can specify if you want to send speed data to strava, and how you want to send it.

The options will be:

  • Yes/No - Send Speed data to Strava

Then if you choose “Yes”, you’ll get these two options:

  • Send Trainer Speed
  • Send Virtual Speed (based on physics model)

Sounds great @Nate_Pearson Is virtual speed based on a speed from power factor?

On Strava you can choose to hide stats like speed so that no-one asks you moronic questions.

@Nate_Pearson thanks! Now we can stick a fork in this discussion thread.

Which would be a better representation? Trainer or virtual? :wink:

Whichever is greater :thinking: :rofl:

I’ve just come on this forum to complain about this and I’ve seen this bug is being fixed.

Bravo TrainerRoad.

Yes. Just a simple physics model. There are assumptions of course, but it should get you a lot closer than trainer speed.

This sounds like part of a much larger and very exciting update.

This is great.

Any way this can also be done retroactively and thus removing speed / distance for past rides too?

Thanks

Glad to hear! I was worried that the option to have miles sent would go away. I’m guessing since there’s going to be a “virtual speed” that we should be able to get mileage totals based on a power meter while riding rollers without a speed sensor now?

Edit the ride your self and you’ll be able to hide the speed/ distance stats now Strava is upgraded. It’ll be a laborious process though depending how many rides we are talking about :neutral_face:

Quite a few rides, but the issue is that I would like to have indoor distance removed from my stats in general.

Just as laborious (probably more in fact), you could use FIT File Tools to strip distance entirely for both you and your strava friends. I’ve used fit filetools on an case by case occasion to remove stats (usually stupid power or heart rate spikes). I’d find it simpler to ignore turbo distance myself and use veloviewer to see the split of indoor and outdoor miles. Alternatively and definitely more laborious you could also edit the gps file.
