"The Melloblocco bouldering competition (or should that be 'celebration'?), has evolved over a few years from attracting a small number of climbers to an international event drawing in a crowd of over 1,500 people in 2008.
This year saw three days of bouldering in three areas of Val Masino and the Mello valley, with hundreds of problems for everyone to go at. Of these, a small number were for the
'serious' competitors, marshalled by local guides who recorded names on a clipboard, to later be collated into a list of who climbed the hardest problems, split into male and female categories. For everyone else, the hundreds of other problems allowed you to try your hand at a whole variety of styles of climbing, with slopers, heel hooking and small, sharp crimps being common.
The atmosphere at the event was tremendous; people climbing 3a and 8a sharing bouldering mats and spotting each other, with none of the elitism that could have crept in."
