Next Sunday, April 26, 2026, the streets of Santiago de Chile will transform into the country’s largest running stage. The Santiago Marathon, Chile’s most iconic race, will bring together tens of thousands of runners to celebrate a true sporting and social event. In this guide, you’ll find the race’s history, start times, course details and practical tips to make your experience unforgettable.
History and significance
The origins of the Santiago Marathon date back to 1909, when an early race was held at the Hipódromo de Chile. After decades of sporadic events, the International Santiago Marathon was established in 1990. In 2007 it adopted its current name, and since 2008 it has been held along Alameda Avenue, with both start and finish lines in front of La Moneda Palace. With more than 30,000 participants in its latest edition and a World Athletics Bronze Road Race label, it is the largest sporting event in the country. The organizers also promote the Maratón Social Foundation, which focuses on civic engagement, solidarity and sustainability.
At the elite level, the men’s course record belongs to Kenya’s Luka Rotich (2:09:39 in 2017), while Peru’s Inés Melchor holds the women’s record (2:28:18 in 2015). In 2025, Chilean runner Carlos Díaz won in 2:09:50, highlighting the rising standard of South American distance running.
Start times and distances
The 2026 event features three distances with staggered start times to improve logistics:
- Marathon (42 km): starts at 07:40 from Alameda. Ideal for experienced runners aiming to push their limits.
- Half marathon (21 km): starts at 08:10, 08:25 and 08:40 to reduce congestion. Only hydration stations will be available.
- 10 km: starts at 08:00 and 08:10. Perfect for beginners or those looking to enjoy the atmosphere.
All participants share the unique experience of running with the Andes mountains as a backdrop while crossing the heart of Santiago.
Course and route features
The start and finish lines are located on Alameda Avenue, in front of La Moneda Palace. The 42 km course passes through iconic neighborhoods, crosses major avenues, skirts urban parks and runs near the National Stadium. The profile is gently rolling, with small elevation changes and a slight downhill finish that helps runners pick up the pace.
The half marathon shares much of the full marathon route but returns earlier toward the city center, while the 10 km course is concentrated in the historic district. Hydration stations for the half marathon will be located at kilometers 5, 10 and 15, with no food provided. A notable climb around kilometer 10 requires smart pacing.
Training tips
Coach Constanza Gutiérrez and other experts recommend following a structured training plan and avoiding last-minute improvisation. Key tips include:
- Consistency over intensity: avoid sudden increases in mileage to reduce injury risk.
- Strength training: work on legs, hips and core for better stability and endurance.
- Practice nutrition: test gels and drinks during long runs.
- Prioritize rest: proper sleep is essential for recovery and performance.
- Don’t compare yourself: every runner has their own journey—enjoy the experience.
The organization offers structured training plans (18 weeks for the marathon and 14 weeks for the half marathon), developed with Nike, combining workouts, recovery and nutrition guidance.
Nutrition and hydration
Sports nutritionist Araceli Bernales recommends adapting your nutrition strategy to the race distance. For 10 km and 21 km, strategic caffeine use may help reduce perceived effort.
- Bring your own fuel: especially for the half marathon, where no food will be provided.
- Use hydration stations: located at km 5, 10 and 15.
- Avoid congestion: move slightly past stations before drinking.
- Adjust your strategy: in the marathon, take gels every 40–45 minutes and alternate water with sports drinks.
Registration, Expo Running and logistics
Bib numbers typically sell out within hours. In 2025, more than 30,000 runners participated, and 2026 entry fees are expected to range between $80 and $120 USD for international runners. Bib collection takes place at the Expo Running held at Estación Mapocho, where you’ll also find brand booths, talks and runner-focused activities. Arrive early to avoid long queues.
Community and sustainability
Beyond competition, the Santiago Marathon is a celebration of the running community and social commitment. The Maratón Social Foundation promotes inclusion and environmental responsibility. The 2025 edition was carbon neutral, and the organizers aim to continue sustainable practices in 2026.
Final thoughts
Taking part in the Santiago Marathon means experiencing a powerful mix of effort, achievement and camaraderie. Whether you run the full marathon, the half or the 10 km, prepare well, take care of your nutrition and enjoy every kilometer.
