Exercise lost?

[Xiggo]

Hello,

Today i ran my first 5km. I was so happy i finished it without stopping for taking a breather.
At the end of my training i pressed Finished on the android app.

I took a glass of water and returned to my cellphone. I  found out that my exercise is totally gone?
The only thing i could see after 5 minutes waiting is they recorded the minutes of my exerice and the heart rates. But there is no GPS data?
I am sure it was on when i started my training. I could see my map and the green bars that there is a gps signal.

Does anyone know if i can still retrieve some file on my cellphone?

I think something went wrong when i entered the house. I think my cellphone connected to my wifi and was uploading data to fitbit. I left my house to stay outside for 5 minutes because it was very hot  inside after the training.

My cellphone lost the wifi signal and something there went wrong. I think.
