Fast pace hike/scramble up Mt Ossa.  All participant must feel strong for a big day (25km, 2300m d+) covered at a good pace with some scrambling at the top of the hike.  Feeling comfortable in class 3 scramble is important.  Everyone must be comfortable and have the appropriate gear for the terrain.
