Ridden in lots of places around the world, but not around it.
Wife and I quit our jobs, getting on for 10 yeras ago. Rented the house out, packed everything up and flew to Australia with pannier-laden bikes. Rode across Australia (cheated and got the train across the Nullaboor) and back. Rode up and down the length of NZ, then on to California. Realised distances in the US are big, so rented a car for a week or so to get to the Grand Canyon and Yosemite. Left it in San Franciso, rode north inland, then out to the coast and down the PCH to LA.
All in, I think it was a mere 8000km in 18 months which is a very, very slow average speed. We stopped a lot 🙂 Life-changing time though.
