From organizer:
The Flint Hills are home to some of the most beautifully rugged gravel roads in the US. These challenging courses feature some of the most scenic rolling hills through the Tallgrass Prairie.
Although some blacktop roads will be necessary from time to time, the vast majority of the course will be on gravel and dirt roads. Some of these roads receive little to no maintenance throughout the year and can be quite primitive in nature.
In the event of inclement weather, gravel, and dirt roads can become mud roads. Riders are therefore encouraged to prepare their bikes, their bodies, and their minds to be ready for any and all possible conditions.
