Course subject to change according to the necessary approvals.
The Irontrail is an extremely long, high alpine trail that is extraordinarily challenging from a technical, physical and psychological standpoint. Some parts of the course are very exposed. In order to complete the Irontrail, experience in running on alpine terrain, an outstanding capacity of orientation, adaptability, self-reliance in the mountains and an excellent level of training are necessary. Acclimatisation at the relevant altitude (over 1500 m above sea-level) for at least five days before the race is strongly recommended (see acclimatisation). The minimum age for entrants is 18 years.
For course knowledge, detailed study of the route maps is essential. Runners must be prepared to find the race route using the map. This becomes particularly important if the course markers are missing due to wind or outside interference.
