Photo 97 of 100 :: Day 4, Sunday, 5 May 2002 So I made it to St. Charles. It was a really fun bike ride, even if the photos make it look like a plain, flat, straight trail. It IS a low-impact trail, but you can make it as high-impact as you want by increasing the distance you ride each stretch. Plus, if you're going against the wind, it's that much harder. Especially if you get the song “Running Against the Wind” stuck in your head, like I did the first day.
