Automatic 10 Mile

Bypass the drawing and guarantee your entry into Minnesota's most popular fall race.

Just like the Minnesota state bird, the common loon, a TC Loony runner is strong, active, agile and distinctive! These runners are hardly common, though - they challenge themselves to run three races in one weekend. The TC Loony Challenge includes the three Twin Cities In Motion events during the Medtronic Twin Cities Marathon Weekend - totaling 19.3 miles.

Series Celebration

As a TC Loony Challenge participant, you'll receive access into an exclusive, heated tent on Sunday to celebrate your weekend. Meet fellow series participants, fill up on hot coffee, a catered meal and dessert, and pick up your 2019 series swag! Show your bib for tent access.
