I am a couch potato so I would be starting from scratch. 20 years ago I was pretty good at working out and seriously considered competing. I did do bike rides and we even biked one of the volcanos in Hawaii. Now I'm starting out again. I want a bike. I would be doing sprint duathlons. No way will I swim. I need a bike. I used to have a Cannondale I loved, but unfortunately I can't afford one of those right now. Is there a bike you use as a weekend warrior that is under 200 you can recommend until I can afford more and know I will stick with this at my advanced age?
