Pricing, Packages & Extras

All packages include accommodation and all the meals from the eve of the first stage till the breakfast on the Sunday after the last stage. Further, you will be supported during the stages with an event director, feed stations on every mayor climb, a day bag for your personal equipment and nutrition, GPS live tracking, a media car, and a broom wagon in case something doesn't go 100% to plan. In the meantime, we transport your luggage to the next hotel. 

Most of the support is the same for everyone, with one notable exception: the accommodation. To cater to different preferences (and budgets), you can choose between three options:

Budget
Accommodation in shared rooms, hostel-style

Comfort
Accommodation in twin/double hotel rooms (3 Stars or equivalent) with your team partner or another rider of the same gender

Single
Accommodation in a single hotel room (3 Stars or equivalent)

The earlier you register, the easier for us. Therefore, we offer Early Bird rates till April 15 for the Inferno Dolomites & Slovenia. Regular registration will be available till May 31, roughly 15% more, and if there are still any spots left, followed by the late registration window.

Team spirit or going solo? Inspired by ski mountaineering races, the Inferno Series has been exclusively a team event till 2022. Both riders in the team complete the whole distance, it is not a relay. 

Hearing about the challenges of many of you in finding a partner for the race, we opened the events to solo riders since the 2023 season. The race in teams of two stays at the core of the race – it can be very helpful to have a partner on your side when the riding gets tough. 

But if you prefer to face the challenge solo, you can do so. And we are sure that the community of cyclists and the support by our team will ensure that you are never really alone on the road.

We offer transfers, massages, Friends & Family Packages, and in cooperation with BCYCLET, rental bikes as extras. All extras are subject to availability, the earlier you book them, the better.


For the Inferno France we offer the following transfers. The transport of your bike is included.

September 30
Venice/Treviso Airport – Bruneck

October 05
Bovec – Bruneck
Bovec – Venice/Treviso Airport

Friends and family are very welcome at the Inferno Events – and you can book a package covering their accommodation and meals with us.

We are also looking for a small number of volunteers to support the events, this is a great opportunity to follow the cyclists if your partner, spouse, or friend is riding! Please contact us for volunteering.

If you want to ride your own bike, we offer as an extra to transport a flight case/bike box for you from Bruneck to Bovec. 

Boxes from our partner Buxumbox are transported free of charge!

In case traveling with your bike is proving too challenging, BCYCLET has a special offer for rental bikes for you. The rental bikes will be ready on the 30th of September in Bruneck, and collected on the 5th of October in Bovec
