A bit of a bizarre one. When adding a manual treadmill run I put the title as follows "60 mins @ 17.0kph." When saving the run it will only show "60 mins @". If I keep editing the run to add the speed back in it won't show when saved. However if I edit it to show "60 mins @ 17.0kph" (note without the full stop at the end) then it will save fine. The same happens whatever the speed entered, it seems like Strava doesn't like full stops!
Obviously it doesn't bother me, just a peculiarity with the software that seems a little strange!
