In 2017 the 3 Dams and 5 Dams Challenge will be held on Sunday April 2.
In past years the event has played havoc with BMW Motorcycle Club Sunday rides.
2,000 cyclists participate on Darling Scarp roads stretching from Mundaring to Kingsbury Drive.
A good day to head to Toodyay, Bindoon, Gingin or Guilderton.
