So I am starting my SB trek on or around July 22. I will have to leave the trail and get back home to Atlanta for a few days in October. Is there anyway to guess how far I will be so that I can book a flight/bus ride/any mode of transportation to get home? I plan to complete in 4-4.5 months. I know it will be a slower start than finish, but having trouble trying to figure it out. Any suggestions?
