The main feature of the 2026 edition is that the full routes will not be disclosed in advance. No GPX files or detailed profiles will be provided beforehand, requiring participants to rely on the course markings set by the organization.
Blind Trail Sprint - 17 to 20 km: This is the main distance of the event. During the race, athletes will encounter a Decision Point and choose between approximately 17 km (shorter distance, but greater elevation gain and more physical and technical demands) or approximately 20 km (longer distance, but less elevation gain and a more rolling profile).
Blind Youth Trail - 10 to 12 km: This maintains the exact same strategic concept. Approximately 10 km offers a shorter route with greater elevation gain and demands, while approximately 12 km offers a longer route with less elevation gain and more rolling characteristics.
Mystery Walk - 6 to 9 km: Walkers will also have to make a decision during the course. The approximately 6 km option is shorter but has more elevation gain, while the approximately 9 km option is longer with less elevation gain and a more accessible path. The walk is not timed.
