Organizers of the Missouri River 340, the world's longest non-stop paddler race from Kansas City, KS, to St. Charles, MO, have elected to cancel the ultramarathon race for 2011 due to a high likelihood the race course will be flooding at the scheduled date.
The race had registered over 340 boats for the 2011 event, which was to be the sixth annual run of the race. Near certainty of above flood stage river levels for most of the race course caused race organizer Scott Mansker to look for a new alternative. In order to give an option for racers who have been planning for months on the original July 19-22 dates, Mansker's organization, Rivermiles, elected to move the race to an alternative location, 150 miles of the Kansas River, from Manhattan, KS, to Kansas City, KS.
