Trans-Kansas (KS)
Admin note: The record across Kansas has likely been set on a Trans America run. Mike Wardian has the fastest supported time that we could find.
The route provided is just one possible example. Any start/end points on the western and eastern borders may be used, in either direction.
One possible route is from Kanorado on the west border of Kansas to Kansas City, Missouri on the east side of Kansas, following old highway 24 for most of the state.
