Racers to reach Jefferson City checkpoint on day two of Missouri River 340

JEFFERSON CITY, Mo. (KMIZ)

Safety measures are in place for day two of the MR340 race, as the Jefferson City Carl R. Noren Access checkpoint opens Wednesday morning for the longest non-stop river race in the world.

Hundreds of racers are paddling the river in this annual statewide race, which began Tuesday in Kansas City. The Carl R. Noren Access in Jefferson City is checkpoint number three along the race route and racers must check in with the race officials by 4 p.m.

There were a total of 652 racers who started in Kansas City and 465 boats, which is 100 more racers than in 2025.

The MR340 is a race with non-motorized boats, kayaks and canoes heading 340 miles down the Missouri River to the finish line in St. Charles within the 85-hour time limit.

Several safety boats are stationed around each checkpoint and paddlestop to check for any racers who might need help. In areas where there may not be a safety boat nearby, all racers are expected to assist other racers needing safety assistance.

To compete, racers must have the required gear, such as a life jacket, which must be worn during the entire race, and a cell phone with extra battery life and navigation lights for travel.
