Course
The Viña del Mar Half Marathon course
The Viña del Mar Half Marathon runs on Sunday, April 4, 2027, over 21.098 km, with a 5K on the same morning. Both distances are measured and certified to World Athletics / AIMS standards, and the race is backed by the Chilean athletics federation (FEDACHI).
Read the full course notes
The course uses closed public roads in Viña del Mar and runs beside the sea, and the organizers publish the final map with splits, elevation and checkpoints in the Runner's Manual before race day. Each distance has its own start window (20 minutes for the half, 10 for the 5K), the half has a 3-hour limit, and every finisher receives a medal.
- Distances
- Half marathon, 5K
- Weather on race day
- Early April in Viña del Mar is mild and usually dry, with average highs near 19 °C and lows near 10 °C. The chance of a wet day is only about 3%, humidity is low, and a light breeze of around 14 km/h tends to blow from the south. A cool morning start by the ocean is ideal for running well, so bring a throwaway layer for the wait and plan to shed it once you are moving.
What to train for
A certified seafront half rewards steady pacing, so build tempo runs of 6 to 10 km at goal half marathon pace and finish long runs of 16 to 20 km a little faster than you started.
The 3-hour limit gives plenty of room for first-timers, so if this is your first half, focus on consistent weekly running and a long run that grows by about 1 to 2 km each week.
Practice drinking on the move, since aid stations follow the intervals in the Runner's Manual. Check the published map once it is out and rehearse any rises it shows.
