Congrats on the new bike! Hope your wrist pain gets better. That doesn't sound good.
I did my first group ride this evening, a small group (10) of women. I was the only one not in shape, but managed to keep up well for the first 18 of 20 miles. The wind kicked up at that point and it started to rain, and I huffed and puffed the rest of the way back and fell 100 yards behind everyone, though caught up again in the last half mile. I'm still nervous getting close to others' tires, but tried to keep within a couple feet when I was feeling brave, though noticed my whole body tensed up when I got closer than two feet and had to concentrate on relaxing. Had a ball and hope to do it again soon.
