The Murray to Moyne Cycle Relay is an annual event in Western Victoria Australia. It is a 520 km cycle relay from Echuca in the North to Port Fairy in the South. A team of (usually) 12 cyclists, 4 drivers, and 2 support crew take on this challenge (and yes they are all Type 1, usually) to raise money for both HypoActive and Type 1 Kids Camps around the country.
While being trapped in a cramped bus and cycling lots of km over 24 hours sounds pretty off putting, you will find it is a great experience. Everyone on the bus gets it and has a great time. Think of it as T1 camp for Adults.
