I recently downloaded new software ver 1.6.26 on my runner 2 & have run 3 times since. I earned 1600+ for these runs. However when I look at my fitness age on Sports App it shows 72 yrs! I'm 65 yrs old, female and run 3-5 times a week at ave HR of 160+ for 30-60 a time and run from 5-10kms. The Trends page shows that my Fitness age has increased from 50 yrs average to 72 since using the new software. Whilst I know this calc is wrong I'm alarmed. It should at least be a bit lower than my chronological age.
Am I the only one with this problem?
