What Have I done?

OH MY GOD. I signed up to have a personal trainer whip me into biking shape.. I knew I was in trouble when I first spoke to her. I told her my 200km bike goal, and her eyes just LIT up! I'm actually terrified of my first "be prepared to workout" session on Saturday. She doesn't use any equipment just props, so I'm in for a treat. She did give me a heads up that by April (or any good non snowy day) she wants me to bike to the gym. That's like 30km on bike paths. I know I know 30k is just a step to 200km but man it seems like reality now and I'm scared. :D But again I can do this. This is nothing compared to watching Dad fight cancer.
