I have a contact in my contact list som every begining of the month can clear all the Garming challeges in the first day.
in exempel:
run 80 km
walk 146 km
swim 4000 m
bike 400 km
bike climb 3000 m
4 hours work out
and more.
But it is time impossible to do that in just one day, physicly I am also concernd abou it. The method is he creatres activities manualy and they are hidden. But the system does not check the start time to understand that in reality it is not possible to do that.
My question is: is it possible to Garmin to develop blocking that?
