Liability

The organizer may change the route at any time. The organizer is not obliged to refund the entry fee in the event of changes to the route or cancellation of the event due to force majeure.

Please throw away waste directly at the refreshment stations, otherwise carry it with you to the next station. Throwing away bottles or other waste outside the refreshment zones is prohibited and will result in disqualification.

The mountain bike course may only be completed with a mountain bike that complies with the regulations. This means no road racing handlebars, tire diameter at least 38mm (1.5"), no aerobars.

No accompaniment and no poles are permitted on the mountain running course.

Depending on the weather conditions, the treacherous upper wind on Lake Thun can turn the swim into an exhausting discipline.

Parking spaces for supporters will be signaled. Please pay particular attention to the exact details in the athletes' briefing, which will be available from August.

Competing in a race like the INFERNO Triathlon requires thorough and serious preparation. Experienced INFERNO participants offer you their experience as part of the training planning.

The road bike course takes place on public roads that are not closed off for the race. The Road Traffic Act applies. Violations will be punished with disqualification.

Schilthorn

Reaching the finish line on the Schilthorn triggers unforgettable feelings of happiness. Warning: danger of addiction!

Safety

The safety of the athletes is the top priority at INFERNO. The organizer reserves the right to change routes or cancel disciplines if the safety of all participants cannot be guaranteed.

Sunset

Insider tip from the race director: If the weather cooperates, the finishers who reach the finish on the Schilthorn after 20.00pm will experience beautiful sunsets!

It is also possible to travel to Thun by private car - signalized parking spaces are available behind the Hotel Holiday (Supporter parking lot). Arrival via A6 (exit Thun-Süd). Please arrive early, as only a limited number of parking spaces are available. Free parking only with 'Team Trophy' sticker until 9.00 am.

Swiss Tri

The INFERNO Triathlon and the Team Trophy are organized according to the regulations of the Swiss Triathlon Federation (www.swisstriathlon.ch). The race will be supervised by referees from Swiss Tri.

The INFERNO participants are looking forward to the support of spectators along the route!

Preparation for swimming

Before the competition, the pools at Thun Lido are available for swimming in.

Replacement route

If the swimming discipline cannot be carried out due to the weather, a 3 km running course must be completed in Oberhofen. Single athletes are therefore asked to take their running clothes with them to the start in Thun if the weather is uncertain. All athletes will be transported to Oberhofen by boat from Thun Werft.

With its 5,500 meters of climbing, the INFERNO Triathlon is considered one of the toughest triathlons in the world. Along the way, it is quite possible that one or the other participant will have to struggle a little. But the finish is all the more beautiful and emotional afterwards.

Traffic roules

The roads are not closed off, so there is zero tolerance for non-compliance with the traffic rules. Disregarding the instructions of the marshals or failing to comply with the traffic rules will result in immediate disqualification!

Transition zones

All equipment must be deposited in the transition zones in Oberhofen, Grindelwald and Stechelberg at check-in on Friday. The organizer will transport the participants' equipment to the Stechelberg transition zone after the race. The equipment can be collected here on Saturday evening or Sunday morning.

A full-body wetsuit is mandatory for the swimming discipline.
