I went 20 miles today on my Trek 2.1, and it was cold! It only got to 40 degrees today, but it was sunny. There was no way I could work up a sweat, no matter how hard I pedaled. I didn't even bother to bring a water bottle, but I did gulp 2 glasses of vegetable juice when I got home. I told the pastor at church that I'm not tithing anymore, and I bought my bike instead.
