It would be nice to be able to form a group ride, impromptu, similar to the group workout feature, where one is rubber banded to another cyclist (maybe more than just one). There are friends that I would like to cycle with but don’t as they are stronger than I.
I found by adjusting your weight or that of your other friends you can all ride with the same wpk. That should allow you one option without an enhancement. The other option is an enhancement to Zwift to provide some option to ride not by wpk but by % of FTP. That way everyone riding at 80% of FTP would be riding together.
