Warmup and events should produce separate FIT files

When doing an event (group ride, race, etc.) with a free ride warmup before, Zwift is producing one single FIT file. When importing this in e.g. runalyze, the file contains jumps between locations (when user is beamed to start) that messes up distance, etc. Also, the warmup and the event can not be distinguished. Better would be to separate the activities and produce and upload two FIT files. Could also be a setting to allow combined or separate activities.

All I know is when I do an event that Strava lists 2 rides. One being whatever I did before the event and the event itself from when the gun goes off. These rides can be downloaded From Strava and uploaded to other sites e.g. Trainerroad. Zwift is splitting these rides up for me. I don’t have to do anything. Pretty sure it also creates 2 fit files in the activities folder. You do however get just one log file that combines warm-up and the event.

I definitely only have one file from my event on Saturday. But: your post rings a bell for me: if I remember correctly, it depends how long the warmup phase is if two or only one file are being produced.

From memory if your warmup is under 2km it doesn’t get sent to Strava.

Not sure if Steffen is using Strava.
But if he is, he can also split the file: https://support.strava.com/hc/en-us/articles/221033867-Activity-Split-Tool

Thanks! I used fitfiletools to cut off the warmup.

It’s in 3 parts: Lets say you start riding, say 10-15 minutes before the event A, and then autojoin the event 5 minutes before and do a warmup B, and then you ride the event C.

Zwift will record A as one ride, it will only record the time for B but no other data (and will only record the time implicitly in the timestamp of file C, and finally it will record C with full data but the first data point in that file will be the start of the event (even if the timestamp of the file will be at the start of B) so the warmup time in the start pen is lost.

Be aware also that data in activity A does not count towards missions and challenges. I lost calories toward the 10000 and elevation toward Everest that way.
