Unbound Gravel

About the race

The biggest day in gravel, brutal, iconic miles across the Flint Hills of Kansas. Late May / early June.

Typical weather

May is spring racing weather: mild but unpredictable, with a real chance of wind, rain, or a surprise warm spell.

Who it favors

Gravel rewards durable all-rounders. You need the aerobic engine to ride for hours, the punch for steep pitches, and the discipline to pace your own effort and fuel when there is no group to hide in.
