I was reminded today that when riding on smooth pavement you need not be so mindful of the riding surface as when riding a path. A small dip in the road sent me flying because I wasn't paying attention. Yet on the dirt paths and trails where the surface was much more irregular I was definitely paying attention and had no real problems staying on top.
That dismount got me thinking about mindfulness while riding, and paying attention to each stroke, each movement, regardless of the surface. It is tiring, and maybe not necessary, but I'm going to work with it the next few rides and see where it takes me.
