The half course is an out-and-back that starts at the eastern end and heads west about 6.5 miles before returning.

Aid is available at specific mile markers: water near miles 3.3, 6.5, 9.8 and 12.2; Gatorade at miles 3.3, 6.5 and 9.8; and food at the Panorama aid station mainly for 50K runners. The event operates cupless racing - runners should bring their own hydration vessel or HydraPak SpeedCup. Packet pickup locations and dates are listed in advance.
