Official trail running information for the Ijen volcano region covers the full range of published race distances, from the longest Blue Fire Trails at 105 KM to the shortest Blawan Trails at 19 KM, with the Kawu Trails at 75 KM and the Blau Trails at 46 KM in between. Every category begins in the Ijen Volcano area, so runners can select a route that matches their preparation level and then review the race map for their chosen trail before the start. The longer routes take in the crater rim and the famous blue fire phenomenon, while the mid-distance and shorter categories move through volcanic terrain and the marked trail network, giving competitors a clear choice based on experience, endurance, and confidence on uneven mountain paths.
