Concerns had been raised about the event after warm temperatures left the Organising Committee of the competition struggling to prepare a course for the season finale in the Swiss resort.

"In a tremendous effort of willpower and work, the Organising Committee in Schonach has made it work to hold the World Cup Finals 2017 in spring temperatures," the FIS said in a statement.

However, the difficult weather conditions have forced organisers to shorten the format for the event, which will now feature one jump followed by a 10 kilometres cross-country section instead of two jumps and a 15km race.

Snow had to be collected from the Black Forest region and taken to the venue so that the jumping hill and the track could be prepared for the World Cup, which is set to provide a fascinating conclusion to the campaign.

Frenzel and Rydzek, who has never won the World Cup crystal globe, have traded the lead throughout the duration of the season.

Frenzel is chasing a record fifth straight title and currently leads his compatriot, winner of four gold medals at the recent FIS Nordic Ski World Championships in Lahti, by 14 points.

He has 1,534 points, with Rydzek trailing in second on 1,520.

The 28-year-old usurped Rydzek at the summit of the standings with victory at the previous event in Trondheim to ensure he went into the concluding competition in pole position.

"Due to the snow situation, the format for the last day on Sunday was changed from two jumps and 15km to a normal one jump, 10km Individual Gundersen, a total of 200 World Cup points are still up for grabs on a final weekend which could not be more exciting," the FIS added.

Action begins tomorrow with the qualification and provisional competition round.
