Course Descriptions

The Dirty South Roubaix offers several distances to ensure every rider finds their perfect challenge. The terrain is famous for its "rollers" - short, steep hills that accumulate significant elevation over the course of the day.

Course	Description
100K+	The flagship distance. This course takes riders deep into the forest, featuring the most significant climbs and technical gravel sectors. It is a true test of endurance for those looking to conquer the full Dirty South experience.
Single Speed 100K+	Designed for the purists who prefer one gear. This category follows the full 100K+ route and requires a unique blend of strength and momentum management to master the rolling hills.
