Fitness App data lost

Hi, I recently upgraded my iPhone. The data transfer and the whole process worked fairly well.

While reviewing the data transfer in health I realized that I had as “sources” three different Apple Watches (I have only had one). Out of impulse I erased one of the “watch data sources” just to realized that I had erased some of my history.

The activities of those “gone” days stills exist (from Runkeeper) but the data is missing and my streak gone :-(

Anybody can think of a way to recover that lost data? Thank you in advance
