First ridden by �Davo Jones� (RIP) back in April 2007 and certified as a BBG2500K. Sadly, Davo passed away on Friday, September 4, 2009, as a result of hitting a deer on US-95 shortly after crossing into the U.S. from Canada during the 2009 Iron Butt Rally.

In 2011, President of the Iron Butt Association, Mike Kneebone, in recognition of Davo�s tireless efforts for the long distance riding community in Australia and in the encouragement, support and promotion of the IBA there, renamed the ride to the Centreline 24 and added the Centreline 36 to complete the series of rides.

Davos� comment:

As part of a ride called "The Long Ride" to Darwin as a fund raiser for The Royal Flying Doctors I decided to return home the long way. Completing 8395klm (5216mi) in 8 days along the way including 2 days not riding.

I had been thinking about doing a centre line run under 24hrs from Darwin in the Northern Territory straight down through the deserts to Port Augusta in South Australia. After a lot of consideration and talks with locals I phoned my wife back at home on Saturday the 29th to say "darling I have decided to try and run the centre under 24hrs, it's 2700klms" to which she replied "I thought you might"

I will write the full report later. But for now it seems I may be the first to do this as a documented and witnessed IBA ride.

I like to call it "CentreLine 24" now let�s see if anyone else wants to take up the challenge. For those out of the country, we are talking almost desert the whole way with very few inhabitants.
