Most of my riding up until a couple of years ago was with a couple of mates or a bunch of club members. Over a period of time things changed; 1) my mates either moved away or quit riding, 2) I began getting fed up with some of the clique attitudes amongst club riders, and 3) certain club rides were on days/times that just didn't fit in.
One thing that really pi55ed me off, and still does, is "leaders" or groups that won't listen to any input from other riders who perhaps know the area better and want to explore a certain area or have a valid reason for wanting to include a particular trail, etc. It's almost like they switch into robot mode and have to follow the trail that's in their head. Really annoying.
Hence most of my recent riding has been solo or hooking up with the odd person (including some who might well be odd) here and there. Thankfully I have no problem with motivation and can quite happily head out for a 2 hr quicky or a 4-5 hr exploration. For me it's about keeping fit, having a laugh, not taking things too seriously, pushing myself, exploring, taking in the scenery as the seasons change, find that new trail I've heard about, re-visiting an old-skool trail I haven't done in years, and generally appreciating life in a reflective kind of way.
That's my tuppence anyway.
