Geronimo, the cliff like drop into Ogden Clough, has got to be one of the best/worst/most suicidal/brilliant/spectacular/horrid/most arse sliding/most ball breaking <delete as appropriate> descents going. Its also quite along way down. In many respects sticking to the boggy and bouldery track that aims you diagonally down the hill/cliff face is the safest route to follow..... but it is slower. A lot of runners go down to the right where it can be faster but more dangerous. I threw myself off the top last year and ending up sliding down much of the way on my backside.
