Course
The Media Maratón del Mar course
The Media Maratón del Mar Sistecrédito celebrates 10 years in 2027, with 10,000 places across the 21K and 10K and a kids' race the day before. Runners take organizer buses from Castillogrande, Bocagrande, Manga, the Centro and La Boquilla to the start at the Sociedad Portuaria de Cartagena, where the 21K leaves at 5:20 am and the 10K at 5:50 am.
Read the full course notes
Local press describing the organizer's route has the half running through Manga and along the bay, past the Castillo de San Felipe, into the walled Centro Histórico through the Torre del Reloj, then out along Bocagrande and Castillogrande before finishing beside the Centro de Convenciones. Water is offered about every 2 km, with isotonic drinks at some stations, and corrals are assigned by expected finish time.
- Distances
- Half marathon, 10K
- Weather on race day
- Ten years of late February weather data for Cartagena show average highs near 32 °C and lows near 24 °C, with about 27 °C by 8 am. February is in the dry season here, with rain on only about one day in eight, so expect clear skies, sea breeze and humid air from the start. Run the first half conservatively, drink at every station and save your push for the last few kilometres.
What to train for
The course follows the bay and the old city, and it is run in Caribbean heat and humidity, so getting used to the heat is the big training theme.
Build to a long run of 18 to 20 km, and do some of your runs in the warm part of the day to train sweating and drinking.
Practise taking a cup every 2 km without breaking stride, since that is how the aid is spaced. With a 5:20 am start, rehearse a few early wake-ups and breakfasts so race morning feels familiar.
