I went on a group ride today with a dozen friends and it made me realize how much I miss the longer mountainous rides. For years I have done about 100 group rides per year but recently backed off and started riding mountain bikes on Saturdays, (I still do the shorter 25-30 mile club rides on Sundays).
Anyway I wasn't able to keep up on the climbs, (nothing new), but they waited and it reminded me of some great times I've had with smaller groups of the right people.
I've also had fun with larger groups blasting around the city. I don't think I ever want to go only solo.
