B & D meaning

Hi, hopefully a quick one. Last week I ran a group 10k and had a “D” next to my name; this week same run and I had a “B” next to it - can anyone help me to understand what this means? Thanks, mike

I’ll bet that it has to do with which pace group you entered the event with. Do you recall signing up for the D group last week and the B group this week? I imagine Zwift automatically adds the group letter to your name to make it easier to find other runners in your pace group that you can try to hang with. Look to see if the other runners have letters after their names.
