Overview

Held in Lake Hovsgol National Park, Mongolia Sunrise to Sunset takes runners across forests and lowlands on a 100-kilometer trail route with 1860 meters of climbing. At 18.6 meters of ascent per kilometer, the profile is moderate, but runners share the wilderness with an exceptionally small pack—the race has a smaller field than 83% of 100k events and is bigger than just 15%.

The 18-hour time limit demands an average pace of 10.8 minutes per kilometer. This cut-off is more generous than 57% of 100k peers and tighter than 43%, allowing steady pacing over the distance without leaving unlimited room for prolonged stops. Organized by ecoLeap foundation, the event carries an entry fee of 1980 US$ for its August running.
