GVBR meaning in General ?

The Great Victorian Bike Ride, commonly known as The Great Vic, is a non-competitive fully supported eight- or nine-day annual bicycle touring event organised by Bicycle Network. The ride takes different routes around the countryside of the state of Victoria, Australia each year. The total ride distance is usually in the range of 550 kilometres (340 mi), averaging about 70 kilometres (43 mi) a day excluding the rest day. The ride first ran in 1984, attracting 2,100 riders in what was initially supposed to be a one-off event, but due to its unexpected popularity and success it subsequently became an annual event. The Great Vic typically draws several thousand participants each year, with a record of 8,100 riders in 2004, which makes it one of the world's largest supported bicycle rides.
