Indonesia Trail Running Boom: Roads to Mountains

The Shift to Rough Terrain and Ultra Distances

Runners across the country are trading asphalt for uneven paths, driven by the desire for shifting landscapes and physical challenges. Fitri Utami, a 45-year-old Jakarta-based worker, told Xinhua that she prefers trails because she can enjoy the scenery and converse with others without obsessing over her pace. After starting with her first trail race in 2023, she has competed in Bali, Yogyakarta, Bromo, and the Dieng Mountains, and recently completed a 100-kilometer race in Bandung. She recalled running 80 km from 4 p.m. to 10 a.m. at the 2024 Coast to Coast Nite Trail Ultra in Yogyakarta, finishing barely five minutes ahead of schedule through terrain that included beaches, gardens, cemetery roads, and thick mud.

The Indonesia Marathon website indicates that hundreds of trail running events have been held in Indonesia in recent years, with at least 51 competitions scheduled for 2026. The country’s diverse topography features routes ranging from 15 kilometers to ultra-trail races spanning mountains, forests, valleys, rivers, plantations, and coastal areas. Current competitions navigate Mount Rinjani in West Nusa Tenggara, the Merbabu and Lawu mountains in Central Java, alongside Bromo, Dieng, Bali, Bandung, and Yogyakarta.

Regional Dominance at SEATRC 2026

The domestic boom coincides with elite international success. At the SEATRC 2026 event held from July 24–25 at Mount Gede Pangrango National Park in West Java, Indonesia’s team dominated the vertical 7km category against competitors from nine ASEAN countries, as reported by rri.co.id. Putra Aldio from Jakarta won the men’s race by clocking 1 hour 3 minutes 54 seconds, edging out Filipino runner Christone Dinawanao and Thailand’s Surachat Thaesi. In the women’s division, Fitri from South Sulawesi claimed gold with a time of 1:20:59, finishing ahead of Cambodia’s Laurie Phai and Thailand’s Pitchanan Mahachot.

Donny Gahral Adian, team leader and Secretary General of the Indonesian Trail Running Association (ALTI), praised the performance as reported by rri.co.id, stating they hope to secure more golds to emerge as the overall champion. Marciano Norman, Chairman of the Indonesian National Sports Committee (KONI), noted that the achievement should inspire other runners to aim higher for the nation, according to rri.co.id.

Mental Health and Physical Resilience on the Trail

Beyond competition, participants emphasize the mental health benefits and rigorous demands of off-road running. Hazet, a 43-year-old runner who took up the sport after COVID-19 pandemic gym closures, told Xinhua that he enjoys how the terrain constantly shifts between dirt, rocks, sand, and forests. He recalled spending two nights on the trail during the Bromo Tengger Semeru 100 Ultra with only ten to fifteen minutes of deep sleep. Similarly, Purwaji Santoso, 38, noted that tackling tough terrain helps him decompress from work-related stress and explore his physical limits.
