Sillassen Half-Marathon & 5K

Presented by Village of Arthur

Attention: For the safety of our athletes, volunteers, and race officials, the 2018 race has unfortunately been canceled. 

The National Weather Service expects blizzard conditions for this region of Nebraska, beginning Friday night and continuing through Saturday morning. These conditions, sadly, make it unfeasible for us to safely hold this year's race.

While we strive to hold races whenever possible, rain or shine, we hope our athletes understand that sometimes it is simply not possible. In accordance with the event policies of the Platte River Fitness Series and Sillassen, refunds will not be issued. Please refer to your race waiver for more information about these policies. 

Race Information

The Sillassen Half-Marathon will take you to the renowned Nebraska Sandhills for a challenging, scenic half-marathon. Running on the historic Sillassen Ranch, the race will take you through stunning, hilly vistas. A challenge to those who want one, and a great first half-marathon for those looking for an unassuming place to give the distance a try. There will also be a 5K for everyone else which will start at Arthur City Park. The Sandhills will make you stronger!
