According to event organisers Rare Management, the event has brought a £30m boost to Highland tourism since it was first hosted in Scotland in 2002.
Renowned as one of the must-see events on the Scottish sporting calendar, over 250,000 fans have descended on Fort William since its launch 14 years ago.
Mike Cantlay, chairman of VisitScotland, said: “This is a fantastic figure and a gives a tremendous boost to the Highland economy.
“It really is testament to the great organisation of this incredibly popular annual event and the multitude of spectators it attracts from all corners of the globe.
“The visitor economy causes a ripple effect that touches every industry, business and community in the country – from laundry to life sciences.
“This news perfectly illustrates how important events such as the UCI Mountain Bike World Cup in Fort William are to tourism in our regions.
“Tourism is more than a holiday experience – it creates jobs, sustains communities and provides a shop window for business activity.”
The event is supported by EventScotland, Visit Scotland and Highland Council.
