runner)? How do I train for a triathlon, especially the swimming and biking parts? I've never been a competitive swimmer or biker before. If I'm gonna be doing a sprint triathlon this summer, what should I do for the swimming? and biking, what kind of bike will I need to get (I don't have one I can really use, and not looking to spend a stupid amount of money on a bike...) and what kind of workouts should I do for that? Thanks
