The Inception of Dirty Kanza
Dirty Kanza, the precursor to Unbound Gravel, began as a grassroots initiative, conceived and realised by a small group of cycling aficionados in Emporia, Kansas.

The founders, inspired by the rugged beauty and harsh conditions of the Flint Hills region, envisioned a race that would challenge the cyclists’ physical stamina and their mental resilience.
Dirty Kanza’s focus on community involvement and the spirit of adventure set its early days apart. The founders emphasised the importance of not just the race itself, but the experience of coming together, sharing stories, and overcoming obstacles in unison.
