Great question, Brandi!
I didn't start biking as a conscious decision... was more lead to it. I used to go to the gym for step aerobics. One day my knee had a total blow out during step class. There was a lady I knew who told me to start coming to the spin class instead. My reaction was, "No way, it sounds like the instructor is trying to kill everyone in there!" She was like, "If I can do it, so can you." (She's in her 70s). So I tried it out, and loved it. Well, one thing lead to another...got the shoes, got the bike. Now I'm hooked and hope to love cycling forever!
