The puzzle
From the 20th event of the Great Victorian Bike Ride in 2003, Bicycle Network began giving the rides catchy names for improved marketing, christening that year's event the "Summit to Sea". That year, for the first and only time in the ride's history the Great Vic journeyed into Victoria's alpine areas. The route then descended along the scenic Great Alpine Road for 175 kilometres to its end in Bairnsdale, before travelling through Gippsland and finishing in Mornington, the first time it had ever finished outside suburban Melbourne.
Question: Where did the ride start? (two words, no spaces)
