Ride not tracked

[MTK1919]

Hello all. 

I have a pixel watch 3 and use the Fitbit app to track my cycle rides. I use this often and it's generally faultless. 

Tonight however, I got about 2 mins from the end of a 50km ride and the battery went on my PW3. 

Assuming it would have saved something, I charged the watch and when I powered it up it flicked up briefly something about the previous activity stopped but data saved. However no matter where I look on my watch or my phone I can't find it. Weirdly it does show cardio zones following my ride but not exercise data. 

Any idea how I can retrieve this? It was a really strong ride too so I'm very keen to see the stats. 

Thanks

Welcome any thoughts on this. It was a particularly strong ride from a time perspective and probably hit a good few PB's. It's driving me nuts that data isn't somehow stored for later review. I'm not even bothered about it syncing to Strava, just want it for my own records.
