2nd attempt today. Gave the calibration another shot. Before calibration, i was seeing the difference (between the pace on my Garmin, and the pace in Zwift with the Tickr X) to be about 45seconds/km to 1:00min/km.
ie: Garmin showing 4:45min/km. Zwift showing 5:30 - 5:45min/km
After calibration, it was more like 15-30 seconds per km difference. (Zwift still reporting slower pace relative to Garmin)
In the screenshot, you can see that Zwift reported 8.88km, compared to Garmin 10.4. HOWEVER, keep in mind that in Zwift, there would have been elevation changes, and the pace would not have changed, therefore the distance covered is expected to be less.
Two more things to try:
- Another calibration, to see if i can get it more accurate
- i forgot to set the Garmin to do the auto-lap every 1km - so i don’t have the split times to compare to the splits in Zwift! (want to see on a per-km basis the spread between the two)
