We have a yearly alternating schedule for our events. The 164km non-stop race, known as the S1 Ultra, was last held in 2023 starting from Gorizia, and is set to return in 2025.

In the intervening year, 2024, we’re hosting the Ipertrail, which is a staged race covering a total of 166km, allowing for a different kind of experience and challenge for our participants.

However, if you’re specifically looking for a non-stop long-distance challenge in 2024, we would suggest combining the “La Volpe del Carso” stage of the Ipertrail with the 80km Night Trail.

The “La Volpe del Carso” stage, from Nanos to Volčji Grad, is planned for Friday, 5th January 2024, starting at 8:00 am. This segment covers 36km and features an elevation gain of 1190m, taking you on stunning trails with vistas of the sea, valleys, and vineyard-covered hills.

Following that, you could participate in the 80km Night Trail, which spans 81km with an elevation gain of 2707m, and offers a thrilling experience of running under the night sky.

This combination would simulate the demands of a non-stop long-distance race and provide a unique challenge. Please note, however, that undertaking these races requires significant physical and mental preparation due to their length and intensity. Make sure you are ready and have considered all necessary logistical details before committing.
