The Lima42k, also known as the Maratón de Lima, is Peru’s flagship road race and the largest marathon in the country. Held each May in the capital city, it attracts a mix of local athletes and international visitors seeking a well-organised event in South America’s coastal Pacific climate.

The course is flat and fast, taking runners on a tour through several of Lima’s neighbourhoods, including San Isidro, Miraflores and Surco. Much of the route follows broad boulevards and coastal avenues, with few technical turns or changes in elevation. The wide roads and straightforward design make the race especially appealing for sub-3 runners looking for even splits.

May is autumn in Peru, meaning conditions are often ideal for racing. Mornings are cool, with temperatures in the mid-teens Celsius, and humidity is lower than in the summer months. While fog and overcast skies are common, they often contribute to favourable running weather.

Crowd support is strongest in the city centre and popular coastal areas, while quieter zones still benefit from well-placed hydration points and enthusiastic volunteers. The event is known for its efficient logistics and professional feel, with clear pre-race communication and reliable on-course support.

The sub-3 cohort is sizable, particularly among Peruvian club runners and regional elites. While not a deep international field, there’s usually enough pacing company for strong amateur athletes to run competitive times.

Lima42k is an excellent option for runners in South America or those looking to combine a serious race with travel. Its combination of fast terrain, stable climate and competent organisation makes it one of the most attractive marathon choices in the region for sub-3 aspirants.
