As a marathoner, you’ve probably heard of (or even dreamed of completing) the legendary ‘Big Five’ marathon races across Berlin, Boston, Chicago, London and New York City. But for those based in Asia, there’s a world-class alternative much closer to home. Enter the UTMB World Series’ Trail of the Kings – Lake Toba, a brand-new trail event in Indonesia.
Marking UTMB’s first foray into Indonesia, this trail celebrates not only the country’s spectacular landscapes but also its rich Bataknese culture. Its name, Trail of the Kings, pays homage to the ancestral kings of the region. The course winds through the rugged terrain of Lake Toba, Indonesia’s largest volcanic lake, surrounded by dense tropical forests, steep ascents and descents, and sweeping ridge lines. Runners will traverse trails that skirt the crater rim, offering panoramic views of turquoise waters framed by sheer cliffs and lush highlands – it’s the sort of scenery that tempts you to pause mid-race.
Participants can choose from five distances: 5km, 10km, 28km, 60km and 100km. There’s also a kid-friendly course designed for young runners aged 7 to 12.
