The tenth day of the Grand Australian Ride starts at Caiguna in Western Australia and ends in Norseman in Western Australia. I explored the Caiguna Blowhole. This region has a network of caves and the blowholes regulate the pressure. I rode on the 90 Miles Straight road which is 146.6 kilometres in length. It is the most straight road in Australia. I stopped at Balladonia for Fuel and some coffee. It was a hypnotising experience. The total ride was 376 kms and took 7 hours 25 minutes approx. I finished at the Norseman and stayed at Great Western Travel Village Motel. The ride was straight and the traffic was very low. I purchase dinner at a petrol station near the accommodation. I had had Potato Hashbrown, spinach roll, juice and noodles for dinner.
