Napa Valley Long Run ???

Hi all,

Going to be in Napa Valley this weekend, for some R&R.  However, I'm "bringing my running shoes", as I am training up for a marathon in December.  Looking to do a 16 mile run +/- on Sunday, our last day there (Alexander Valley Lodge, 20507 Geyserville Avenue, near the 128/101 junction.

Anyone know of a "great run" location??  My plan is to "go west", Canyon Road to Dry creek - then either follow the Vineman route backwards, or maybe go up into the Lake Sonoma Rec area. 

Any ideas??

Thanks,

Dennis
