Viña del Mar Half Marathon
Race Day Weather
Cool start — fast day potential, warming through the race
A cool 48°F at the start line is ideal for fast times — expect to warm up quickly once you're moving. Temperatures rising to 63°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing. Moderate humidity at 69% is worth noting for effort level, especially in later miles.

Race Info
The Viña del Mar Half Marathon is a World Athletics-certified course that starts at Reñaca beach and runs south along Avenida Borgoño, Avenida Jorge Montt and Avenida San Martín. It crosses the Puente Casino to Avenida La Marina and continues west on Avenida España to the front of the Universidad Federico Santa María, where runners turn around. The return retraces the coastal avenues to a finish on Avenida Ignacio Carrera Pinto near the start, on a mostly flat out-and-back route.
