Maratón De Santiago

The Maratón de Santiago is Chile’s largest marathon and one of the most prominent road races in South America. First held in 2007, it has grown into a major fixture on the regional running calendar, attracting tens of thousands of participants across multiple race distances. The event is staged in the heart of Santiago, with both the start and finish located in front of the Palacio de La Moneda on the Alameda, the capital’s principal boulevard. Set against the backdrop of the Andes Mountains, the race offers a distinctly Chilean urban experience, combining modern city districts with views of the surrounding landscape that dominates much of the Santiago basin.

The course is run entirely on paved city streets and follows a broadly looped route through the capital. Although often described as relatively flat, it is better characterised as gently rolling. The marathon accumulates approximately 177 metres of ascent and 171 metres of descent, with elevation changes spread gradually across the distance rather than concentrated into major climbs. A notable feature is the highest point of the course, reached at around 30 kilometres, before the route begins a generally descending run towards the finish. The layout takes runners through a variety of districts, showcasing Santiago’s wide avenues, commercial centres and residential neighbourhoods while maintaining a largely uninterrupted rhythm on broad urban roads.

Conditions are typically favourable for marathon running. The race takes place during the Chilean autumn, when temperatures are generally cool at the start, often between 5°C and 10°C. As the morning progresses, temperatures usually rise into the 15°C to 18°C range. Humidity is typically low, creating dry and comfortable running conditions compared with many major city marathons. Rain is possible but uncommon, while clear or partly cloudy skies frequently allow uninterrupted views of the Andes, which remain visible from many sections of the course.

For sub-3 runners, the Maratón de Santiago presents an appealing balance between speed and challenge. The moderate elevation changes require more attention than a completely flat marathon, particularly approaching the high point around 30 kilometres, but the profile remains manageable for experienced runners. The predominantly downhill final section can reward disciplined pacing, allowing athletes who conserve energy through the middle stages to finish strongly. Combined with cool temperatures and generally dry conditions, the course offers a realistic opportunity for a sub-3 performance while still demanding enough variation to prevent it becoming purely a time-trial effort.
