(It being summer in the northern hemisphere, maybe everybody has been out riding, hence the seemingly low number of new threads in this sub-forum. Regardless, the time seems ripe to put out there an idea I've had for a long time.) Judging from riders I've met, I was wondering if MAYBE the rider that finds long distance motorcycle rides easiest is not somebody that exercises everyday, but someone who doesn't exercise at all, somebody that is skilled at inactivity, somebody that can sit for long periods of time with only occasional reason to get off the couch? In contrast, those people that are USED TO moving about, having lots of blood circulation and muscle movement are more likely to find the relative inactivity of long distance riding more uncomfortable. Runners, group sports regulars, gym rats--seem less likely to be doing long rides. The sample of riders I've met that can ride all day without complaint are guys that I'm reasonably sure have never exercised a day in their lives. Maybe I simply have not met enough people that regularly exercise? I'm not sure if the "sedentary" rider's body is just better used to relative inactivity or there are other physical characteristics that come into play. Maybe it is mental? Me, I'm not a good test case. I rarely do marathon rides anymore and only exercise when my alcohol consumption catches up with me! Maybe the periods when I did regularly exercise left me too fatigued to ride for long periods. Maybe I need to develop a theory about something else entirely.
