20 years of the most remote and beautiful ultra-trail running, 20 years of charity for Hovsgol National Park and its population: The anniversary Mongolia Sunrise to Sunset (MS2S) 42km and 100km trail run took place in early August at the shores of mighty Lake Hovsgol in Northern Mongolia. Runners from no less than 15 countries took part in this exceptional challenge and witnessed first-hand why MS2S is widely considered to be one of the most beautiful trail runs on the planet: Lakeside trails, windblown lowlands, craggy mountain passes, mossy fairy-tale forests and meadows full of wildflowers. The runners pass by wild yaks and horses. Mongolian horsemen serve as race marshals. Jun Matsumoto from Japan claimed the 100km victory in 12:37 hours. Among the ladies, Austrian Cornelia Oswald was the fastest (16:04 hours) to overcome the very challenging ultra-distance with an accumulated elevation gain/loss of 3.375m.

In the days before and after the race day (August 7), the participants stay at a picturesque camp at the gorgeous Lake Hovsgol, sleep in traditional Mongolian “Gers”, enjoy outdoor activities such as horseback riding, kayaking, hiking, fishing and daily yoga sessions. They also get in touch with the local population and get a glimpse into their unique nomadic lifestyle. The race itself is as challenging as it is beautiful: The accumulated elevation gain/loss in the marathon distance is more than 2.200 meters, in the 100km ultra run it is 3.375 meters. Still, everybody with a strong spirit and good training can complete the race. The cut-off time – for both 42km and 100km – is 18 hours.

Through the ecoLeap foundation, garbage trucks are bought, park rangers hired, eco-friendly garbage bags provided.

It was an outstanding event – not to be missed. I have often been asked to name the race that I enjoyed most. My previous hesitations to name my favorite event are now replaced by a certitude: Mongolia Sunrise to Sunset.”
