The shirts are ready! The shirts are ready! And we've got the pictures. Runners who register for the BTN Big 10K by July 1 will receive a gender-specific, sized technical race shirt corresponding to the Big Ten school of their choice. After July 1, inventory is not guaranteed, so early registration is suggested.

Ohio State great Eddie George is this year's Grand Marshal for the July 25 event in Chicago. The Heisman Trophy winner and former Tennessee Titans running back will also take pictures with fans. Now in its fourth year, the BTN Big 10K has become one of the top 15 largest 10Ks drawing fans from 48 states and eight countries last year.

The event will be held just before Big Ten Media Days, which officially kicks off the 2015 football season. A few more key links here:

And now, let's check out the shirts below.
