Outdoor Ride Duration Shorter in TrainerRoad Than in Garmin

My outdoor ride duration is displayed shorter than expected in TrainerRoad.

I record my rides using a Garmin (Forerunner 955), and the data is synced to TrainerRoad and Intervals.icu.

The attached data is from yesterday’s outdoor ride.

In Garmin, the ride time was 5:23, and the total elapsed time including stops and traffic lights was 6:03. However, in TrainerRoad, the duration is shown as 4:44.

When I look at the power zone distribution, Zone 1 (including 0W) was only about 12 minutes. Even if that entire 12 minutes were excluded, the difference in ride time still does not make sense.

What could be causing this discrepancy?

Was your power, hr, and cadence really that steady? Asking because of the ride profile showing some steeps.

It’s odd that the graph shows 5+ hours and no stops, but the numbers don’t.

Thanks for taking a look and asking.

As I mentioned in my original post, in Garmin the ride time was 5:23, and the total elapsed time including stops and traffic lights was 6:03.I am attaching the Intervals.icu data as well. I took a 15-minute break at the midpoint of the ride, and the rest of the stopped time was due to traffic lights.The 5:23 represents the ride time excluding those stops, and 6:03 includes them.In other words, even after subtracting all stops and breaks, the duration should still be 5:23 — so it still does not explain why TrainerRoad is showing 4:44.

Today’s ride time was shortened again in the TrainerRoad data.

Were there truly zero stops like the TR graph shows?

In the Intervals.icu data synced from Garmin, the blacked-out sections mark the point where I took a break, and there were also occasional stops for traffic lights elsewhere along the route.

In the Garmin data, the elapsed time from start to finish is about 5:39, and the moving/ride time is about 5:05—so those two values are consistent. However, the data shown in TrainerRoad is not consistent with that.

Thanks! In addition, it’s also strange that in the TrainerRoad calendar, the Garmin time is shown correctly

It’s odd that your stop time is showing power and cadence data. Could it be that? Totally guessing here.

That’s just how Intervals.icu displays it. The x-axis is time, and there’s no data recorded while I’m stopped, so the points right before and after the stop get connected with a straight line.
