In reply to Eric the Red:
If you're in town and want to keep it simple, a good route is up to scout scar. From the centre of town, run up Beast Banks (a road that runs west out of town) all the way up into Underbarrow Road until you hit the scout scar car park (circa 2.5 miles). Just after there's a gate on the left which ultimately leads to the plateau above scout scar. From there the world's your oyster, just keep running along the top of there until you've had enough then follow your nose back into kendal.
The views and surroundings are awesome and because of the perspective, the chances of you getting very lost is slim to none. Not the most hardcore route you'll ever do, but a very accessible and straightforward one that gives you a bit of everything. You could easily create a 10 miler out of that.
Either way, enjoy your time up there.
