Ultra-marathon kayak race movie premiere in KC tonight

It takes a kernel of crazy to paddle across the state of Missouri on a river known as dangerous and dirty in the blazing summer heat.

It takes almost as much determination to try to capture the blood, sweat and tears with a single video camera.

In 2007, filmmaker Jodi Pffeferkorn took her first stab at the Missouri River 340, an ultra-marathon kayak race from Kansas City to St. Charles, but quickly found that covering scores of paddlers over hundreds of miles was no easy feat. “It was a good first attempt, but I knew I could improve on it,” she says.

So last year, with the annual race having grown from 15 friends with a crazy-ass idea to 255 boats from all over the country, Pfefferkorn decided to give the documentary a second try.
