Thanks for everyone's feedback. I have decided to take two pairs of pants with me. My Sauconey running pants which are very comfortable and can be worn over padded bike shorts and my Eddie Bauer lightweight long pants for off the bike. I am also trying to minimize weight on my cross country tour but decided having two pairs of pants is worth the extra weight. As many folks have mentioned, I can adjust this as I go, sending items home and picking up other items as needed
