Runners can choose 5K and 10K park races in the early morning, a 50K or 100K ultra that starts late at night, a 24-hour championship format, or a five-person relay that covers 100 km in 20 km legs. The course is flat and runs on asphalt roads inside the park, repeated over several loops with the same start and finish point.
