Marathon season is upon us, and Nike's been hard at work to help get you ready for the big race. Just last week, Nike dropped the Air Max Lunar1 "Chicago Marathon", and today we get two more options for runners to lace up when they take on the Windy City.

Nike dropped two Chicago inspired versions of their premier runners for this year, the Zoom Structure 18, and the Pegaus 31. The Nike Pegasus 31 "Chicago Marathon" comes in a black mesh upper, and is complimented by blue and orange hits through the outsole, sock liner, and midfoot area. For the Zoom Structure 18, Nike flipped the script and did the shoes in a orange base with blue accents on the Flywire, sock liner and outsole. Both shoes feature nods to the Windy City with the official marathon logo on the insoles, and "CHI" stitched into the heel area.

Both pairs of the "2014 Marathon Collection" are currently available at the Nike Store.
