Course & Elevation

The Lima 42K, officially the Maratón adidas RIMAC Lima 42K, is a road marathon in Lima, Peru, held on a Sunday in May and run by the organiser Peru Runners with adidas as title sponsor. A half marathon runs over the same circuit. The race starts before dawn on Avenida Larco outside the Miraflores town hall and follows Avenida Arequipa through Lince and San Isidro towards Cercado de Lima, turning near the Paseo de los Héroes Navales and coming back along Avenida Arequipa. The circuit also takes in the Miraflores seafront walkways, including the Malecón Cisneros, the Malecón de la Reserva and the Villena Bridge. The half marathon is one circuit and the marathon is two laps, finishing on Avenida Larco. The first edition was held in 2009 at the Pentagonito with 7,000 runners. Since 2022 the race has been run from Miraflores on a route inspired by the Lima 2019 Pan American Games. The time limit for the marathon is five hours, set because the city closes the streets for a fixed period.
