I just registered for the ING Miami Marathon 01/30, the Hyannis Marathon 02/27, and the Publix Georgia Marathon 3/20.
Miami is flat and fast, so I do expect a good time - perhaps a personal best. From what I understand Hyannis is a tough race, hilly and sure to be windy and cold. Atlanta is very hilly from start to finish, with miles 23-26 uphill.
