Between February 2002 and March 2003 I circumnavigated 12,504 miles around the Australian continent on my bicycle, or push bike as they say there. After that I went to New Zealand for three months and met up with a friend and ended up pushing the total mileage to 14,115.7 miles (22717.02 km). I spent 269 days on my bike, 272 days not on my bike, and getting 67 flat tires over those 17 months.
I started and ended my 13 month lap around Australia at Luna Park in St. Kilda/Melbourne.. The distance around Australia (including Tasmania) ended up being about 20,281km (12,600 miles).
One fun thing I did during my trip was to visit six "confluences" , which is where a whole-numbered latitude/longitude mark intersects for The Degree Confluence Project.
