This route is not to be taken lightly by even the most accomplished gravel riders. You’ll have 100 miles of the best that the Flint Hills has to offer before finding a town to refuel in. We’ve pulled out the stops and have given you the green light on the world’s best gravel roads. You will be completely on your own, with little to no civilization in sight, for the first 100 miles before arriving in Madison. You’ll have another pit stop at mile 126 in Olpe. This one is not for the faint of heart!
