Aid stations are placed on both loops with a mix of full stations and water only locations at specified mile points. The 5K is roughly 3.43 miles, half on road and half on trail, with about 243 feet of elevation change.

Additional logistics include packet pickup options at the Cool Staging Area, drop bag locations for the 100K, 50 mile, and 25 mile, pacer and crew rules for the 100K and 50 mile, and finisher awards.
