The geography of the courses utilizes the flat, paved streets of Downtown Danville and the Iron Horse Trail. The Mile of Truth consists of two laps on a loop through the downtown core, while the 5K and 10K courses traverse neighborhoods and the scenic Iron Horse Trail before finishing on Railroad Avenue. In early May, Danville typically experiences pleasant spring conditions with average morning temperatures around 12°C (54°F), warming to 23°C (73°F) by midday. The event village at the Danville Brewery features a vendor expo and a jump house for children.

Logistically, the first 1,000 registered runners receive a tech shirt, and the Mile of Truth offers cash prizes for elite and open categories (subject to a minimum of 12 runners per heat). Packet pickup is available at Forward Motion Sports on the Friday and Saturday preceding the race, and day-of registration is available at a premium. The event maintains a strict "back of the pack" policy for strollers and dogs in the 5K to ensure the safety of competitive runners.
