Relay of Voices: The Great River Run takes shape as an ultra marathon relay race from the headwaters to the mouth of the Mississippi River.

We invite you to join us in this ambitious expedition by foot, some 2,300 miles following the a conjoined path of the MRT or Mississippi River Trail, the official bike trail along the Mississippi River and the Great River Road, a National Parkway.

We will cross over to east and west sides of the river, traveling through all 10 states touched by its current. This May we are mapping the MRT Route for travel by foot. This is an in-depth process that will take several months, and we plan to have a comprehensive set of turn by turn directions for both virtual and real travel by August 1, 2018.

Currently, signage marks the trail all along some of the route. See the links below for State by State maps corresponding to the overall route. Relay will provide coaching and other support if you elect to run the route with us. Reach out to for more information on pricing and preparation.
