Following the Olympic year in London, the 2013 Championships will serve as the selection event for the coveted spots to represent Team USA at the IAAF World Championships August 10 - August 18 in Moscow, Russia. The USA Outdoor Track & Field Championships are also the final stop of the 2013 Outdoor USATF Championship Series, following stops at the Drake Relays and Penn Relays in April, the adidas Grand Prix in May and the Prefontaine Classic in June.

Hosted by Greater Des Moines Convention and Visitors Bureau, Iowa looks to continue long and storied legacy as a track and field destination. Drake Stadium has once before played host to the USA Outdoor Track & Field Championships in 2010, three times the NCAA Outdoor Track and Field Championships in 2008, 2011, and 2012, and 104 editions of the Drake Relays.
