out to the Withlachochee Bay Trail this AM. Headed east and managed to not have the hills whip my butt this time. Turned around and headed west feeling pretty good about my speed and realizing my breathing seemed better. About 2 miles from the Gulf end, I ended up with a flat tire. Hubby had been in front and didn't realize I had stopped. Since he left me in the dust, I decided to get off and walk it to the end thinking he'd miss me and turn around. Well, he had decided to turn off on the dirt road and when he came back on the pavement thought I was ahead and continued on. After about a mile of walking in the 95 degree heat, I decided to stop in the shade, turn over the bike and start changing the tire, only to find out that I didn't have a tube. About that time he made it back and luckily did have a spare in his backpack. However, his hand pump didn't work and mine had issues. Did manage to get enough air in it to turn around and head back to the trailhead. Overall only about 10 miles but I was whipped from the heat anyway.
