Hey guys, I'm biking to my parents house in a month, a 450 mile trek. I work and go to school, both full time, so finding time for training is tough. Right now I'm getting about 15 miles a day, sometimes more depending if I have time for a free ride. What do people suggest for training for this kind of a journey? (I know it's not that long, but I'm starting to doubt myself) And how much time would you plan for the whole trip?
