Went on a nice lil’ bike ride last night, one of my last before my almost foolish endeavor this weekend.  It went pretty well, with the exception of some still-lingering back pain.  Hopefully that is from my admittedly weak trip to the gym on Monday, and not an after-effect of the ill-fated 75-miler a few weeks ago.  Anyway, last night Munkirs & I went on the Mission Hills ride.  Despite a somewhat fierce headwind I got my 17 miles in at a decent pace.  The route took exactly one hour, which by my math averages out to about…  Oh roughly 17 miles per hour.  I managed to keep up with the front of the group, at the expense of my lungs.  I just can’t seem to breathe when I ride at that pace.  I don’t really understand it either;  I’m down to one or two cigars a week and I try to eat healthy on Saturdays and Thursdays.  Just don’t make no sense.
