Racers are making their way to the finish line as part of the Missouri River 340 today and tomorrow.

The non-motorized boat race features over 400 race teams traveling along the Missouri River from Kansas City to St. Charles.

Most of the racers are in either kayaks or canoes, and end up traveling a distance of at least 340 miles.

There are six checkpoints and six paddle stops.

The Missouri River 340 is considered to be the world’s largest nonstop river race and racers do not have to stop, unless they want too.

The race is scheduled to end Friday in St. Charles.
