Swan, I don't have much to add that hasn't already been said. I just wanted to wish you well on your journey and congratulations on the weight you've already lost.

I'd also second what Catrin said about her overuse injuries. While mine took a few years to manifest, I alsot think I wound up with some problems due to too much cycling and too little other activity (like weight and resistance work). Balance is good, but if you struggle with finding other activities you can participate in, more than anything, just keep moving.
