Sold out? We are upgrading the race and we will give you a super extra!

Great news for runners and aspiring runners of the S1 Soča Ultra 100 miles.

We should tell you that we are sold out. 100 bibs and 106 confirmed runners.

S1 Soča Ultra is the first 100 miles of Alpe Adria: the first in North East Italy and Slovenia. This year an even more spectacular route will be inaugurated, entirely marked, without snow, very fast, panoramic and perfect for the winter season

We held meetings with our logistics managers and authorities and were granted permission to add another 20 bibs

So if you want to run the S1 Soča Ultra, sign up now or we’ll talk about it again in 2025… in 2024 there will be Ipertrail, the GPS race.

Any other news? We have added a start, at 10.30.

What does it mean? That if you are a 100 mile runner you can decide at what time to start.

At 7.00 on Saturday, at 10.30 and at 13.30 and at 19.30. We will advise you when to start, but you can decide when you want. The only rule is that we will not let you leave the life base of the 65th km before 21.00. So, the choice is yours, but do your math well. All starts will have the shuttle included.

Why this? To give you maximum hours of light and maximum comfort in the race!
