Strava knows everything, or almost everything... there are a few forms of training that remain 'secret'. I don't want to say too many words about the Corona year 2020. We wish and hope that the new year will be better.
The Strava application is actually not my primary training diary. Nevertheless, I find it interesting when it compiles a summary of my sporting activities at the end of each year. Although I only competed in four orienteering competitions, there were still a few training kilometers.
