I mostly ride with my husband, but we also ride very frequently with another couple. We are very close friends with them because of cycling. We go on vacations with them, both cycling and nordic skiing. I also ride with the female half of this couple, but our schedules don't always mesh. She is a slower rider than me, but we have developed a good "system" for riding together.
We lead rides for AMC and I do some group rides with them, but not as many as in the past. I also belong to another club that does Wednesday rides that mostly people in their 40s and up, who stop to smell the roses. There's always lunch involved. They 're really very nice, but I only rode with them twice last summer. My goal is to do more this summer! The other rides in this club are hammerfests.
I ride alone maybe once, twice a week. Again, not as much as I used to. Usually, my husband will adjust his schedule and we end up riding together.
