As we commemorate 9/11, we thank and honor those who serve our country. There is no other event like this in world! During the day there are 7 races going on at the same time in the same location. The "main event" is the 9 hour and 11 minute ultra run where you run as many miles as you can in the allotted time. Instead of how fast can you run a fixed distance you see how much distance you can pack into a fixed time. The event record is 63 miles, but it was set on a different course. The event record is 63 miles.  This is a new location with a pretty flat layout. 

The course is a one 1/2 loop on the Aspiria business park in Overland Park, KS (former Sprint World Headquarters).  Actual address is 6310 Sprint Parkway, Overland Park, KS 66215

Water and support every 1 1/2 miles.
