The Unofficial Gravel World Championship.

It’s the spirit that 4,000 riders bring with them to the Flint Hills of Kansas for one weekend each spring; the spirit of an event that began with 34 participants in 2006 and now stands as the the unofficial gravel world championship.



Those who are unbound embrace life without limits or restrictions. The word owns many definitions and derivations, but each one ultimately reaches the same finish line.

To be unbound is to be free.
