I'd like to look into getting a road bike so I don't have to use my car as much around town or my short commute to work. I'm not sure where to start looking and I know there's quite a range in price with different brands/types. I have no problem spending a bit more on a bike that will last but would rather save money if possible at the same time. I'm not exactly sure of price ranges either so if someone could help point me in the correct direction so I can become a bit more educated before looking to make a purchase that'd be great. I also run marathons and would like to perhaps get into biking more as a form of alternate training and possibly triathlons. If that type of use would really cause the expense to go up I'd rather stick to my original use, an affordable quality road bike for short trips. Any suggestions would be greatly appreciated. If anyone has experience switching to biking or buying for the first time that'd be great too.
