For the challenge and during my training I will be using a modified Qu-Ax 36" unicycle, assymbled by the excellent team at Unicycle.com but to my specifications. 36" unicycles are not suitable for trick riding but used purely for long distance providing the rider has the strength and stamina to pedal all day. They are capable of speeds in excess of 20mph without too much difficulty, although throughout the challenge I am planning to ride at an average speed of 10mph.
