My race predictor is going crazy

My race predictor is going crazy: since the beginning of June, it toggles my predictions from top amateur athlete (which I am not) to regular amateur althlete (which I am).

The pattern is really weird: every now and then (bit random) my prediction goes to ~3h marathon and every now and then (again random) it switches back to ~4.30h marathon.

The latter is realistic.

Some of my other data:

- VO2MAX ~46

- Lactate threshold 155BPM, pace 5:19

In June I stopped running for 4 weeks to go on holiday.

It looks like it will recover from this. Any suggestions how to fix the race predictor?

  • I do see that you have stated that this is random at times, When the incorrect race prediction time does start to display is it after a activity is recorded or just general sync with Garmin Connect? 

  • I wouldn't say it is after recording an activity. I record appr. 8 rides and 3 runs every week. 
    If you take a look at the screenshots, it started somewhere in June. Since them, sometimes it's OK and sometimes not.

    Sometimes I charge my watch via PC, sometimes not. 

    Considering it acts like this for many weeks, I don't think it will resolve itself.

    Any help would be appreciated. I am training towards a full marathon in November, my 10th, and this race predictor used to be my main KPI to see how I am doing.
