Thanks for the reply. Yes, it is very hilly (mountainous) and challenging. At first I had to stop about every 1/4 mile feeling like I was about to die. Now I can do over 8 miles without stopping! I am just amazed how every time I go I improve just a little bit. 8 miles might not sound like a lot to someone who bikes on roads, but for me, on the hills I ride on, it is a huge accomplishment. I realize that I work out much harder doing this rather than indoor cardio (stationary bike, treadmill, etc.) and it is much more rewarding for me. Plus with every pound I loose, it's just that much less to have to haul up the mountain and it definitely gets easier. It keeps me going! Regarding working out when I travel---I know it's all in my head. I have always been intimidated by going to gyms. All those people who go for the social scene in their little spandex outfits and full makeup.... I think I'm just jealous and comparing myself to them. I guess for me working out has never been glamorous.
