Mystery XP - any way of finding out what the XP was for?

I use Zwift with my AppleTV, installed on a pc Monday to try it out. Nicer graphics imo. Anyway, on my second ride that evening I saw I was probably a ride or two away from leveling up to level 95. I was messing around in the companion app and noticed an unlock message on the main screen. Didn’t notice what was unlocked before it disappeared from the screen. Also noticed I had leveled up to 95, but it was a significant amount of XP added - I was instantly nearly 1/3 finished with level 95.

As luck would have it, I was almost done with the ride when my pc locked up. Really locked up, ctrl-alt-del didn’t bring up task manager, holding power wouldn’t shut it off. Had to unplug and let battery die.

After a while, part of the ride appeared in my activities, I guess it must auto save at certain intervals? Looking at that activity gives no clues about what I did to get that much XP to get me to where I am.

Any other way to figure out what I did to earn that?
