Course
The Cali Marathon course
The Cali Marathon returns on April 25, 2027, with a 42.195 km marathon, a 15K, a 4.2K mini marathon and a 1.6K Kids Run for ages 4 to 9. The race describes its route as a tour of Cali's most iconic streets, with city views, parks and historic architecture, on a certified course that has carried a World Athletics quality label since its first edition.

In 2026 the marathon and 15K started and finished at the Canchas Panamericanas (Calle 9 with Carrera 39), with the marathon off at 5:00 a.m. and the 15K at 7:00 a.m. The 2026 time limits were 6 hours 30 minutes for the marathon and 3 hours 40 minutes for the 15K, and runners were placed in corrals by goal time.

- Marathon, 15K
- Weather on race day
- Late April in Cali is warm and humid, with average highs near 28 °C and lows near 19 °C, and muggy conditions about 95% of the time. April is the cloudiest month of the year and rain is common, with roughly a 40% chance of a wet day. The early start helps you beat most of the heat, so begin at a comfortable effort, drink at every aid station and bring a light layer you do not mind getting wet if showers are around.
What to train for
An early start in a warm city means your training should prepare you for heat and humidity, so do some of your long runs at the same early hour and practice drinking on the move.
Cali sits at about 970 m, so runners coming from sea level will feel a small extra effort and should start a little conservatively.
For the marathon, build long runs to 30 to 32 km and include steady runs at goal pace; for the 15K, tempo runs of 6 to 10 km will set you up well. The generous time limits make this a welcoming race for a first marathon, so focus on consistent weeks rather than speed.

Taper
Tapering for the Cali Marathon
Start the taper two to three weeks before race day. Cut your weekly volume by about a third, then by half in race week, and keep a few short efforts at race pace so your legs stay sharp. With the race on April 25, 2027, your taper starts around April 7, 2027.
