Your group sounds like caring riders who enjoy your company. Group I used to ride with = the same. I was doing SOLO riding even before C-19 and found that Midnight Madness Rides (left house at 12:01AM) were enjoyable although not as fast as when group riding but that's the price I paid for my change. When I did show up for a group ride I would often be asked.... "How many miles you got in, 50?"
Strength and endurance are results of effort made and you should hang on so that some day you can be the one pulling the pack.
