You must be local - I've only heard 1 or 2 others call it the 'Lime field'
This is the old route. After Kinder Low you head for Edale Cross, cross over the bridleway & head down into the bottom of the infant River Sett. (Beeline for South Head, virtually). Then a steep climb out of the valley back onto the old route. You don't have to go over South Head (although Lloyd did last year & still set a new record) - just skirt round it.
SteveT normally comes along around now & posts a map of the route. I seem to remember Phil W. & a few others last year drew a sketch map of the route on the back of their race numbers!
