I'm new to the Garmin platform with my Vivoactive HR that I got at the end of December. I've been using this device to track my runs since I've begun training for a half marathon. I'm confused by the behavior I've seen with the Personal Records in Garmin Connect.
Through my first week of training, I established personal records and broke the records for fastest 1 mile, fastest 5K, and farthest distance. I figured this was just an automatic tracking feature, but as my distances have increased each week, and I've had a few faster times, the system is no longer registering that I've broken a record.
The first 5K record time was established at around 39 minutes on a GPS tracked jog that was 3.55 miles (5.71 kilometers) back on January 1. Then on January 8, I did an indoor run that was 3.81 miles (6.13 kilometers). After uploading my activity, Garmin Connect asked me if I'd like to update my personal record 5K with the 33:48 time recorded on that run activity, so I did. Since then, I know I've hit the 5K mark under 33 minutes on at least one of my runs, but Connect never recognized a new personal record.
If I try to manually set a PR on that activity, it asks if I want to replace the 33:48 time with 50:04. That was the total time of that activity that it took me to run 4.35 miles (7 kilometers). It doesn't seem to be able to recognize what time I hit the 5K mark.
I've increased my farthest distance on my long runs almost every weekend in the first month that I owned the Vivoactive HR. The system never recognizes these personal records. I always have to manually set those as a personal record from the activity page in Garmin Connect. Is the Personal Records tracking feature unreliable, or do I need to do something to make it work again how it was the first two weeks I owned this device?
