The marathon is six laps of a flat criterium-style circuit, so spectators see each runner 12 times from one spot. There are two marathon entries: a professional field with elite entry standards and pro pacers, and a Gold Wave for amateurs with dedicated pacers for finish times from 2:20 to 3:30 and personal bottles at fluid stations. A festive 5K runs the same morning. Entry is through RunSignup, and the race is built around fast times.
