The Dutch landscape is rich in bicycle trails (fietspaden), where participants are not bothered by cars and other traffic.
The fietsvierdaagsen are organised by local foundations, which set a route that the participants are to follow.
When the participants have completed the four days and have passed through all checkpoints, they usually get an award, often in the form of a small medal.
The Drentse Fietsvierdaagse attracts over 30000 participants and is one of over 60 fietsmeerdaagse (i.e. 3 or 4 day cycling events) held around the country each year.
A surprisingly large proportion of the total population of the country takes part in these events.
