There is one large aid station at the start/finish area offering standard items such as chips, candy, fruit, cookies, an electrolyte option, water, and hot food options throughout the event. Aid station food is for participants only. Runners with specific dietary needs are advised to bring their own supplies. Participants may set up personal pop-up tents or small aid stations on race morning in the designated start/finish area.

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