Identify player category during race

[mark-inderhees]

Hi, do you know if player race category (a, b, c, d, e) is advertised via zwift packets or some other mechanism? I've done some digging but come up empty.

Good question, and unfortunately I'm not entirely sure. There's more payload in the packets than what's currently being deserialized through protobuf, so I'm confident it's in there, but I haven't been able to decode all of it yet. You can see some of the undefined attributes here. It just takes a bunch of sleuthing to reverse engineer the packets.

I kind of found it. In player state there is group Id. These are in order of the cats. So if I know my category then I can infer the meaning of group ID.
