Iowa's Greatest Running Tradition.

Since 1980, more than 100,000 runners have made running from the quiet and calm of the Saylorville Dam to the heat and high-rises of downtown Des Moines one of the greatest running traditions in central Iowa. Whether you’re a weekend warrior, a first-timer, or a diehard this iconic running event is for you. 

There is something unparalleled about standing on top of the Saylorville Dam and looking out at the high-rise buildings on the horizon knowing that you will conquer the distance in between. After crossing the dam athletes will travel south through the fields and rural beauty of Polk County.

Runners traverse I-35 at the Morningstar bridge and continue into the Northside Neighborhoods, along the Des Moines River at Birdland Park and enter into Downtown Des Moines via the John Pat Dorrian Trail. Athletes will finish their half marathon journey by crossing the Des Moines River and passing the World Food Prize Building. With the finish line behind, there's a huge party awaiting you at Cowles Commons across from The Des Moines Civic Center.
