Not sure where you can get a copy of the route but, from memory, it goes;
From the cricket club, up through Latrigg woods to the Latrigg Car Park, then up the main path (no going off route!) up Jenkins Hill (I think that's what it's called), follow the main path to the summit, turn around and same way back down apart from an allowed short cut across the grass at the top of Jenkins Hill.
Finish back down by the cricket club.
If you want some more detailed info from loads of fellrunners, head over to the FRA forums and post the same question.
