Ho, man, I had to think of this thread on Sunday...group dynamics never cease to entertain!
I was the new member of a group of semi-skilled riders led by a more experienced/skilled/fit rider – the ride "leader." I just wanted to hang with my friend who invited me, ready and equipped for social pace. I happily swept as we went up and down terrain. My friend was the slowest of the group, so it was easy to hang back with her and have fun.
Near the apex of the ride, I shuffled ahead of the group for some cardio. Said ride leader shows up, chat ensues. A bit of tension seemed palpable; I stay complimentary and submissive. Lastly I ask point blank "do you mind if I go first?" Leader's head swivels away from mine, and she gets on her bike and starts taking off as the others roll up. Did that just happen??? I popped off the trail and passed her, not seeing them at the bottom for a minute or more.
I am baffled as F that I continue to encounter experienced riders who do not get how it works. If someone is on your ass, up or down, in your group or not, they get
the option to pass. Wait for the group at any trail forks. Everyone going as fast as they want. That's not even leader etiquette, just what every rider does or should do.
As for leaders, leave the ego at the car, and take care of your group. Don't blast through trail forks ahead of your noob group. Consider sweeping. Sweep. Move the order around so everybody is mixing it up and not getting bored. Be okay not riding as fast as you might like. Put your focus on the least strong member(s). In essence, use common sense and logic.
Was that a rant?
