After I raised the question about the gates being opened on the Tobacco Road Trail, I decided to email the race officials about it.
Ben Dillon sent back a quick response.
Yes, he indicated the green gates would be open on race day. Which is really good news, the runners will not be funneled down to those narrow passages on the sides.
My other question to him was about the potential of runners/walkers going 2, 3, or 4 abreast on the trail. His response was that they would be requested to be no more than 2 abreast. I will keep my fingers crossed that most people follow this request. If they don't, you are going to see some very frustrated runners.
