I need some advice on choosing a bike. I'm in my mid-twenties, 5'5" and a relatively fit female (exercise 1 hour/day, 6 days/week.) I eat healthy and enjoy an active lifestyle. I want to get into biking to replace my current cardiovascular routines. For the past three years, I've enjoy high intensity interval training (programs like Insanity for example.) I enjoy the challenge of getting into my anaerobic zone and the mental focus required to train so hard. I'm beginning to step away from these fitness practices due to the high impact on my joints (I have knee issues, so running has never been an option) and these programs are not sustainable practices. I've enjoyed recreational cycling but would like to make this a regular part of my fitness regimen.
I think a (fitness) hybrid is the best choice, but it's difficult to define what type of cyclist I'd like to be since the sport is new to me. I figured a little background on the type of fitness I enjoy would help in any bike recommendations. I know I'll be riding on paved pathways and that I'd like the option to go long distances. I've been looking at the Specialized Sirrus Sport and the Trek 7.2 FX WSD.
Feedback is much appreciated!
