Thanks for the great tips Unca_Sam. Local knowledge is the best. I definitely want to spend a whole day riding these Columbus trails. I'll have to come up with a plan on how to make at least some of them in an efficient way. Even so I have a car and flexible, I'll need to ride each trail or segment I choose in both directions. As of now I'm thinking of combining and riding both Camp Chase and Scioto river trails. And then if time permits, I'll add a segment from other trails you described.

My original plan was to bike OTET the first week of Oct, but I switched gears and instead go to an organized cross NC ride. My new plan for OTET is May-June 2022. So I have more time to prepare.
