My wife is an avid trail runner. (I am not...)

We're headed up to Whistler. She's going running while I go riding (though not necessarily on the same trails).

I've found a few links/suggestions for XC trail rides but wondering if there's similar links or suggestions for trail runs, preferably with maps. I suppose she could run the same trails but wondering if there's trails where she can avoid over-zealous DHers on vacation...

Thanks in advance for the help.
