Out in the prairies of northeastern Colorado most of these rural roads are gravel, intercut with the occasional paved road or section. These gravel roads are generally well-maintained and are doable on a road bike. You might be more comfortable, however, if you are able to run at least 28mm tires. Tubeless tires are also recommended if exploring County Road 96 out past Wellington toward Nunn (and beyond). Cell service can be spotty and in the spring/summer puncture vine (or goat head) can be a big problem out here. As the name indicates, this low-lying weed develops hard spiny burs after flowering that are notorious for puncturing tires. Despite this, the gravel roads out on County Road 96 and beyond are loads of fun; you get fantastic views of the entire front range, rolling hills, and isolation out in this rural part of Colorado.
