I fixed a flat on my old Trek 1000. Fixing flats is part of the fun for me. On long trips, I always make sure I have patches and a pump. Once, I forgot to bring my pump, got a flat tire, and I walked 5 miles to get back home.
I put my trek on the turbo trainer today, and did an easy spin for about 45 minutes, I was breathing pretty good. Its not as good as being outdoors, but it will help my body adjust better when I do start riding. I've had that bike for about 15 years, and its still my favorite. Its very comfortable to sit on, and I like having the shifter on the down tube.
