The most recent edition of this event was on 7 July 2017.
The first day of 3 Marathons in 3 Days near Cairns, Queensland has a full 42km marathon and the 21km "Kauri Half Marathon", which covers the first half of the full marathon course.
The event is a 3-day stage race totalling 126.6 kms. Competitors who want to do only one marathon, can enter the Cairns Marathon, which is the same course, date and time as the third marathon of the 3 Marathons in 3 Days. There is also the option to run the half marathon on Friday, and full marathon on Sunday.
Race Founder, Larry Lawson, claims that this ultra marathon came about "by accident", as there was a "Marathon in Three Days" on the race calendar, but Larry said "I'll do Three Marathons in Three Days", and soon he had enlisted other Club Members to join him. Beyond this, it seems to have taken on a life of its own, with a lot of excitement about the event.
