Two-time Olympian Matt Tegenkamp is to make his marathon debut at the Oct. 13 Bank of America Chicago Marathon.

Tegenkamp, 31, has been one of the leading track distance runners in the United States for seven seasons.

The Wisconsin grad from Lee’s Summit, Mo., finished 19th at the 2012 Olympics in the 10,000 meters and 13th at the 2008 Olympics in the 5,000.

He also ran in the last three outdoor World Championships, finishing fourth in the 5,000 in 2007.  He is among six U.S. runners to have broken 13 minutes for that distance.

At last week’s U.S. Championships, he was seventh in the 10,000, failing to earn a place on the U.S. team for August’s world meet in Moscow.
