All finishers registered before the shirt deadline of 9/27/26 will receive event shirts. Any runner who completes at least one official lap in their registered race receives a custom medal.

There is one large aid station at the start/finish area offering standard aid station fare, electrolyte options, water, and hot food throughout the event.
