Stevie,
Taken from the Braveheart site:
Basically the same as the 10 course with a couple of BUTS, these being...
the start is about 3/4 mile up the hill before the 10 start
at the Woodhall roundabout take the 1st exit for approx 3/4 a mile heading up to Woodhall train station
complete a dead turn to head back to Woodhall roundabout and rejoin the 10 course
cross the 10 finish line, go right round the roundabout and back onto the 10 course
repeat all of the above
finish is where the 10 finishes

Hope this helps.
