Today was the first day I used my Forerunner 935. I immediately tested it in two track races: a 3000m race and an 800m race:
* 3000m race: https://connect.garmin.com/modern/activity/1926043892
* 800m race: https://connect.garmin.com/modern/activity/1926043919
Notice that the distances recorded are not correct:
* 3000m race -> actual recorded distance is 3240m (240m extra, which is an error of 8%)
* 800m race -> actual recorded distance is 880m (80m extra, which is an error of 10%)
I have used the Virtual Partner in these races to set a pace, but because of the larger distances recorded, the pace given was too optimistic (which means I thought I was running at a good pace to break my record, but in reality I wasn't...).
Has anyone experienced errors of these magnitudes on track recordings? Can I do anything about it? Or might there be something wrong with my device?
Thanks for your comments,
Bart
