The event, which organisers are hoping will draw around 22,000 visitors, is once again being held at Vale das Almas just outside Faro Airport.


The event is the largest of its kind in Europe, and each year attracts thousands of foreign bikers, mostly from Spain and the United Kingdom.


The four-day event will end this Sunday with the usual procession through the streets of Faro and organisers are once again hoping for an incident-free meet, as has been the case in recent years.


Bikers will also be given the usual dose of entertainment, with a series of events being held throughout the four days.


The headline act this year will be British band The Stranglers, who will be performing on Saturday evening, with Portuguese group Blind Zero opening proceedings earlier in the day.
