Employees of digital microsensors and -systems manufacturer Sensirion AG (Switzerland) have broken the record for building the world’s Longest marble run.

Longest marble run Switzerland

The mark was set at 1,918.12 metres (6,293 ft 4 in) by fellow Swiss company Handwerker and Gewerbeverein Elgg in May, but Sensirion superseded that feat on 1 September 2017 with an incredible 2,858.9-metre-long (9,379-ft 7-in) structure.

The attempt took place at the company’s annual team-building event and saw the colleagues split into 25 groups, each of which constructed a section of the superlative marble run.

The record-smashing structure was assembled in a valley in in Flumserberg, Switzerland, approximately 1,600 metres (5249 ft) above sea level.

"It would have been too easy in good weather," joked Patrick Good, who organised the team-building event.

"The plan went perfectly," said Patrick. "We worked together on the same goal, pushed our boundaries and have been rewarded with the world record for our top performance."

The 1,918.12-metre-long track began in the middle of a beautiful meadow that is filled with skiers in the winter season.

In order to break the existing record, a marble had to roll from the start of the run to the end without any intervention.

Official Guinness World Records adjudicator Seyda Subasi Gemici was on hand to verify the achievement.
