I wasn't feeling too good all day, headache and body aches... I debated big time whether I should ride or not and decide to go out to do an easy short ride. I felt better while I was riding so I went a little longer but kept the ride in Zone 1 Power. When I got about half ways into the ride I had to take a major pit stop so I went to my old High School to use the porta potty out by the track. If I had to go another 10 yards I would not have made it, LOL! Off I go and get 1.5 miles down the road and I get a rear tire flat. A small piece of wire had pierced my tire. it took me about 5 minutes to pull it out, then I checked for anything else struck in the tire, before removing tire from wheel. As I was removing tire I realized I replaced the 80mm valve stem tire and only had 60mm in my fanny pack that I carry with all my spares, tools and other items. Then I realized I did have a saddle bag which should have tubes in it... yes I did, so I was good to go. Put in new tube and off I go. I get home removed all the normal things from the bike and inside I go. What an adventure ride it was, never a boring ride! Be safe out there and enjoy your ride...
