An urban ultra to start spring off with a bang. This event near Knoxville, Tennessee, has quickly become very popular, always filling before the registration closes. With distances from 1 to 150 miles, there's something for everyone.

The course is a fairly flat, paved, generally eight foot wide greenway that is lit at night time. For those who prefer a softer surface, there is grass along side some of the trail. It meanders along the Pistol Creek (hence the name for the event), through Alcoa, by several small bodies of water, and over to Maryville's Bicentennial Greenbelt Park. It is a linear route with a lollipop at the end of the out-n-back and is a bit over 5 miles long.
