2 weeks ago a ride of 120KM 100M elevation and I get an effort of 323 which then goes into my weekly load etc.
Did practically same ride a week later (last Saturday) and got an effort of 4 - which is clearly wrong by 300+.
This in turn knocks out all my stats and data.
Plus I know my VO2 condition status was great.
I don't use Garmin data as the holy grail but its a good indicator for me - and now it is totally shot and will take a week or two to get back to normal - meanwhile I am just about to taper!
Can you not edit the effort or is there a corruption somewhere as a result of the upgrade which happened on the morning of the ride - by coincidence?
