Well, you're welcome to come along and give it a try! Every cyclist should get to ride from Folly Top to Staindrop with a tailwind at least once.
There is a noticeable section of climbing, as you cross watersheds from the Tees to the Swale, but it's nowt compared to the earlier bits, and you can divert around it (but it's not worth the effort IMO as it adds about 5 km).
