HappyAnika - I'm sorry I did not get in touch with you and the other TE'ers who are out there. My experience on the ride bummed me out so much that I sort of retreated into myself. With any luck I'll hook up with you all next year.
I have ridden out there every summer for years and I will have to say that this is the first time I have had so much trouble. The only other difference this time (aside from my anemia) is that my son lived in Breckenridge until last year, so my stay was at 9600 ft. elevation instead of 5280. Not sure that made any difference at all, though...

Again, thanks for everyone's insight and advice....and good wishes. You all are the best!
