Since a few months, you can link your Strava account to TIPPS, enabling an automatic upload of your training sessions to TIPPS (hence not needing to upload the data manually).
All you need to do is to find the connection tab in the settings and click on the connection button. Once you set up the connection, your Strava data will from that date onwards automatically be synchronised to TIPPS. TIPPS will send you a mail once the training has been synchronised and you can click on the subjective feeling (sRPE) for that session to provide you with the training load calculation.
