The adventure stared out nicely until it got sour, at about 6.8 miles I ran over something with both wheels and I could hear the air whistling out of at least one tire maybe both. I pulled over to check how bad it was... it was my front tubular tire that got slashed and went flat immediately. I checked the rear tire too and it was OK. I carry one spar tubular for just this situation. A good driver of a pickup truck with a dirt bike in the back did a turn around to see if I needed a ride home because he seen me walking the bike, I was about 50 yards from a road sign so I walked to it to rest the bake against it. I told the driver I was good and thanked him for coming back to see if I needed help. I pulled off the damaged tire and replaced it with the spar and filled it up checked to make sure it was on good to go enough to get me home. The good thing I just past a cut off that would take me home in 4 miles. So, I go home to change to another alloy rim brake front wheel. Now it is a night ride with a slight modification in the route. I felt half decent on the ride and just wanted to do a good ride, so that's what I did! I wanted to hit some hills because my next 2 TT races have some hills nothing big but enough to make a small difference. I was surprised my back and left knee wasn't in pain, the only thing that was in pain was my neck, holding up my head so I could see where I am going. I finally figured out how to adjust my mirror so I can see behind me in the aero position. The ride went well, looking forward to a phenomenal July and tomorrow's great adventure... be safe out there and enjoy your ride!
