Yes, I would also prefer to be able to set some trainings as "private" and not appear on the public page. Same applies to some pictures (need "private pictues in public trainings").
For me, this is an important decision criteria for future use of gps-sport.
First: I would like to have the choice which trainings and tracks I would like to show to the public and which not. This could be easily implemented by a "make this route/track/training private" button (GPsies has it).
Second: I would like to have the chance to enter heartrate manually after the training online (not only importing it from devices).
Any others who feel uncomfortable with the default "everybody can see everything" setting?
