Race day promises an early morning atmosphere with kit pickup available from 6:00 AM to 7:20 AM for those who registered in advance. Both the run and walk events offer stunning views and serene surroundings along the park's winding paths. The race is timed using chips for runners, while walkers are encouraged but not required to wear their numbers.
