It was made a highlight by Blight's Crows in 93/94.
It basically encompasses ALL aspects of training, running, skills, running, weights, running.
Bit like in marathon days, leading up to the big day which was a 42 km run, about a month before, you might do a 45-50 km run, at slower pace than the event, then taper off and hopefully recover in time. It does work for most.
