I will be making a road trip south down I-77. the stopping point will be in north or south carolina just off I-77. I wont have a lot of time and other people will be with me. I am hoping to get in a mountain run somewhere close to the highway. Time wise i cant drive too far and it will probably be just 5-6 miles of running. I would love trails but that might not be an option. What can you suggest?
