To add to the other answers: There is Sportractive, not open source but European. Using it for nearly ten years now.
Normally I try using Open Source as much as possible but back then there where not that many options and I really like Sportractive so I stayed.
Nowadays they have some premium features but the main parts are still free. Also at some point a second (blue version) was created, no idea why I use the classic red one.
