2014 UPDATE - Race postponed to August 12-15

The Missouri American Water MR340 has been postponed to August 12-15 due to river forecasts projected to be in flood stage from Waverly to Boonville.  Here's the thread on the Rivermiles forum.

Here's the message from race organizer Scott Mansker:

"After consulting with our Water Patrol, Coast Guard, Swift Water Rescue Teams and First Responders along the route, the decision has been made to postpone the MR340 to the designated make up date of August 12-15, 2014. Attached is a link to the form that all paddlers need to complete. Very short form to tell us if you plan on August or wish to defer to 2015. Please fill this out as soon as your family can reach a decision. We are profoundly disappointed that things have fallen this way. It's enormously difficult to plan the race and then re-plan it all over again. We know it's also very difficult for you and your families. But it's the easier alternative than the potentially dangerous situations paddlers would find themselves in on a flooded river, at night, full of debris. We will keep you informed as the August race approaches. Thank you all for understanding. "

Since 2007, Missouri River Relief has been a partner in the MR340 race - a 340 mile paddling race across the state of Missouri. Racers purchase super cool race stickers and all of that money goes to support our efforts. We bring as many safety boat crews as we can and help up and down the race course.

The Missouri American Water MR340 is a true community event - a community created by the river. To witness the determination of the racers, the grit of the ground crews and the hospitality of the volunteers is a truly inspiring thing. We're proud to be part of this amazing event that has changed the way our state looks at our river. Especially thanks to the Rivermiles crew for putting on such an amazing event and Missouri American Water for sponsoring the race.

Below is an archive of articles and info about the race going back several years. Enjoy!

This year was one of the most pleasant races in recent memory, with milder summer temperatures. Lower flows made for a slower race in general, but records were still broken.

This year was dominated by the heat. 3-digit temps on several days. 580 paddlers signed up for the race. About 475 started it and approximately 300 finished. Those that finished used all kinds of innovative tricks to keep cool, from jumping into the river at checkpoints to wearing tube socks full of ice around their necks. You'll see as you read the stories below.

Below are a bunch of links to stories, photos and results from the race. Enjoy!
