About the event
A city that only runs after dark
Night Marathon Ulaanbaatar is the country's largest evening road race. Every distance starts and finishes at Sükhbaatar Square and loops through a fully closed, fully lit downtown course — past the Government Palace, along Peace Avenue, and back under the finish arch while the square is still full.
Distances
Pick your night
Three distances, one start line. Entries are capped per distance and close once the field is full.

Start 20:20 · Ages 18+

Event highlights
What race night looks like
A course lit end to end
Every kilometre is floodlit and marshalled, from the square out to the turnaround and back. No dark corners, no traffic.
Live music every 2K
Bands, throat singers, and DJ stages spaced along the route, plus a drum line at the steepest part of the return leg.
Finisher medal and tee
A new medal design each year, handed over at the arch, with a technical shirt in your race pack at bib pickup.
Chip timing and live splits
Your bib carries a chip that logs the start and finish. Splits go out by SMS so friends can track you from the square.
Fully closed downtown roads
The centre shuts from mid-afternoon. Free late buses run for anyone wearing a bib, in both directions.
Race village from 15:30
Bag drop, warm-up sessions, food stalls, and the expo — open hours before the first gun and long after the last finisher.
Sunset is at 19:42 — the 21K field runs the whole second half in the dark.
