I met a couple who did BRAG last yr. It was from Columbus to Sav and a more flat route w/ some rolling hills (BTW I live in GA) This yr I'm told it a lot more hilly, in the foothills of the GA mtns and 2 people from the local club are gearing up for it. I know this isn't much, but I would be prepared and conditioned for all types of terrain. It is a supported ride via the website. I'd like to do it one day myself
