I did the Mountains to Coast ride last year. It was a great experience.
The event was very well organized and executed. The routes were excellent with only a couple of sections of road a bit too crowded with vehicular traffic. The stops at the small towns in between the overnights were well spaced and stocked with lots of food and drinks. The overnights were also excellent. I stayed in a tent, going with Summit Cycle Solutions for the setup and breakdown each day. I did not use the meal plan but instead ate in the towns (or at a food truck at camp).
I would do it again (can't this year) but would stay in hotels. I did not sleep well in the tent.
I did create a video of my experience as I didn't find much online about it. If you're interested, here's the link to the video: https://youtu.be/2xpgPPwkR4o?si=p2fo2ITfbufutFrV
Bottom line: highly recommend the events put on by NC Sports (Cycle NC), based on my one M2C experience.
