Each year somewhere in Europe is the International Pan Gathering. The first event was held in 1997 in Bristol in the UK. Since then the event has been held in Austria, Holland, Germany, Spain, Portugal, Italy, Ireland, Belgium, Norway and Switzerland.
This event is open to ALL Pan-European riders across Europe and beyond (an Australian couple turned up one year, as part of their European tour), and you don't have to be a member of a club to attend, just have a PAN.
The location for the 2021 event has been announced:
