Added to the event line up as a “stepping stone” to our 200 mile main stage event, the 100 quickly became a race in and of itself. Perfect for those looking for a long day in the saddle, all the challenges of Flint Hills gravel goodness, and just a bit less pain. You will enjoy a solid day of racing and riding and all back in time for enjoying some finish line festivities. Make no mistake, this isn’t all glory – there are plenty of guts needed for this 100 mile jaunt.
