One person's reasonable speed is not another's reasonable speed. I like to keep a good pace going most of the time, that is just how I like to ride. My good pace today is definitely slower and I make more short stops. When others pass me I do not let it bother me, most of the time anyway. I also ride solo at least 95% of the time, so, others pace doesn't affect mine. I have one guy I ride with occasionally, he is a strong rider, and I feel challenged to keep up at times.
